1 What you see in an eclipse is entirely different from what you know. It is especially different for those of us whose
grasp of astronomy is so frail that, given a flashlight, a grapefruit, two oranges, and 15 years, we still could not figure out which way to set the clocks for daylight saving time. Usually it is a bit of a trick to keep your knowledge from blinding you. But during an eclipse it is easy. What you see is much more convincing than any wild-eyed theory you may know.
2 You may read that the moon has something to do with eclipses. I have never seen the moon yet. You do not see the moon. So near the sun, it is as completely invisible as the stars are by day. What you see before your eyes is the sun going through phases. It gets narrower and narrower, as the waning moon does, and, like the ordinary moon, it travels alone in the simple sky. The sky is of course background. It does not appear to eat the sun; it is far behind the sun. The sun simply shaves away; gradually, you see less sun and more sky.
3 The sky’s blue was deepening, but there was no darkness. The sun was a wide crescent, like a segment of tangerine. The wind freshened and blew steadily over the hill. The eastern hill across the highway grew dusky and sharp. The towns and orchards in the valley to the south were dissolving into the blue light. Only the thin river held a trickle of sun.
4 Now the sky to the west deepened to indigo, a color never seen. A dark sky usually loses color. This was a saturated, deep indigo, up in the air. Stuck up into that unworldly sky was the cone of Mount Adams,1 and the alpenglow was upon it. The alpeng]ow is that red light of sunset which holds out on snowy mountaintops long after the valleys and tablelands are dimmed. "Look at Mount Adams:’ I said, and that was the last sane moment I remember.
5 I turned back to the sun. It was going. The sun was going, and the world was wrong. The grasses were wrong; they were platinum. Their every detail of stem, head, and blade shone lightless and artificially distinct as an art photographer’s platinum print. This color has never been seen on Earth. The hues were metallic; their finish was matte. The hillside was a 19th-century tinted photograph from which the tints had faded. All the people you see in the photograph, distinct and detailed as their faces look, are now dead. The sky was navy blue. My hands were silver. All the distant hills’ grasses were finespun metal which the wind laid down. I was watching a faded color print of a movie filmed in the Middle Ages; I was standing in it, by some mistake. I was standing in a movie of hillside grasses filmed in the Middle Ages. I missed my own century, the people I knew, and the real light of day.
6 I looked at Gary. He was in the ftlm. Everything was lost. He was a platinum print, a dead artist’s version oflife. I saw on his skull the darkness of night mixed with the colors of day. My mind was going out; my eyes were receding the way galaxies recede to the rim of space. Gary was light-years away, gesturing inside a circle of darkness, down the wrong end of a telescope. He smiled as if he saw me; the stringy crinkles around his eyes moved. The sight of him, familiar and wrong, was something I was remembering from centuries hence, from the other side of death: Yes, that is the way he used to look, when we were living. When it was our generation’s turn to be alive.
I could not hear him; the wind was too loud. Behind him the sun was going. We had all started down a chute of time. At first it was pleasant; now there was no stopping it. Gary was chuting away across space, moving and talking and catching my eye, chuting down the long corridor of separation. The skin on his face moved like thin bronze plating that would peel.
7 The grass at our feet was wild barley. It was the wild einkorn wheat which grew on the hilly flanks of the Zagros Mountains, above the Euphrates valley, above the valley of the river we called River. We harvested the grass with stone sickles, I remember. We found the grasses on the hillsides; we built our shelter beside them and cut them down. That is how he used to look then, that one, moving and living and catching my eye, with the sky so dark behind him, and the wind blowing. God save our life.
8 From all the hills came screams. A piece of sky beside the crescent sun was detaching. It was a loosened circle of evening sky, suddenly lighted from the back. It was an abrupt black body out of nowhere; it was a flat disk; it was almost over the sun. That is when there were screams. At once this disk of sky slid over the sun like a lid. The sky snapped over the sun like a lens cover. The hatch in the brain slammed. Abruptly it was dark night, on the land and in the sky. In the night sky was a tiny ring of light. The hole where the sun belongs is very small. A thin ring of light marked its place. There was no sound. The eyes dried, the arteries drained, the lungs hushed. There was no world. We were the world’s dead people rotating and orbiting around and around, embedded in the planet’s crust, while the Earth rolled down. Our minds were light-years distant, forgetful of almost everything. Only an extraordinary act of will could recall to us our former, living selves and our contexts in matter and time. We had, it seems, loved the planet and loved our lives, but could no longer remember the way of them. We got the light wrong. In the sky was something that should not be there. In the black sky was a ring of light. It was a thin ring, an old, thin silver wedding band, an old, worn ring. It was an old wedding band in the sky, or a morsel of bone. There were stars. It was all over.1. Dillard describes the setting as being during an eclipse and creates a mood of mystery and awe. 2. Dillard compares the moon to being invisible and the sun going through phases, which creates a clearer understanding of what is happening during an eclipse. 3. Dillard uses language that describes the sky's blue deepening and the wind freshening, which gives a sense of the changing atmosphere during the eclipse. 4. Dillard's word choice in paragraph 8, describing the sudden darkness and the detaching piece of sky, adds a sense of urgency and fear to the text, showing a deeper meaning of the impact an eclipse can have on people's emotions.
cc01fb7eba62c713e218538cA = a; A = normalize(A);在glsl中被优化成A = normalize(a);要怎么避免这种优化
可以使用volatile关键字来避免这种优化。volatile关键字告诉编译器不要优化掉这个变量,即使看起来它似乎可以被优化掉。因此,将A声明为volatile变量,可以防止编译器将A = a; A = normalize(A);优化成A = normalize(a)。例如: volatile vec3 A = a; A = normalize(A);
91c5aeeee515c4fb1dae1751volatile关键字不起作用
虽然volatile关键字可以告诉编译器不要优化掉变量,但在某些情况下并不总是有效的。这是因为不同的编译器对于volatile关键字的实现可能不同,也可能存在一些未知的编译器优化机制。 如果您发现volatile关键字在您的代码中并不起作用,最好的解决方案可能是尝试使用另一种方法来避免优化。例如,可以使用函数调用来强制编译器重新从内存中加载变量的值,或者使用暂时未使用的变量。 例如,您可以将代码更改为以下内容: ``` vec3 temp = a; volatile vec3 A = normalize(temp); ``` 这里,我们首先将a的值保存在一个临时变量temp中,然后使用volatile关键字声明A,并将其设置为normalize(temp)。这样,即使编译器尝试优化normalize操作,它仍然需要重新加载temp的值,因为它是在使用volatile关键字声明的。
e5c5ff9c8e4a676ca50d3f61还是不行
如果使用volatile关键字仍然无法防止编译器进行优化,您可以尝试使用一些其他的方法,例如使用内联汇编代码或使用__attribute__关键字。
使用内联汇编代码是一种强制编译器不要优化掉代码的方法。这需要您对计算机体系结构和汇编语言有一定的了解。以下是一个使用GCC的内联汇编代码来计算向量的长度的示例:
```
float vec_length(float x, float y, float z) {
float len;
__asm__ volatile (
"vmov q0, r0, r1, r2 \n" // 把参数拷贝到寄存器中
"vdot.f32 s0, q0, q0 \n" // 计算向量的长度平方
"vsqrt.f32 s0, s0 \n" // 对长度平方开平方
"vmov.f32 %0, s0 \n" // 把长度存回内存
: "=r" (len) // 输出变量(长度)
: "r" (x), "r" (y), "r" (z) // 输入变量(向量坐标)
: "q0" // 用到的寄存器
);
return len;
}
```
另一种方法是使用__attribute__关键字,它可以告诉编译器不要进行某些优化或指定代码在某些方面的行为。例如,使用__attribute__((optimize("O0")))可以告诉编译器在编译优化方面使用-O0选项,即取消所有优化。但是,这种方法不是所有编译器都支持,并且可能会降低代码的性能。
总的来说,避免编译器优化的最佳方法取决于您的代码和环境,并且需要根据情况灵活处理。373bcd972c32d09c1d1390feglsl/es does not allow precision in this context
在GLSL ES中,precision关键字只能用于数据类型声明中,用于标记变量的高精度和低精度。当您尝试在其他上下文中使用precision时,例如在函数调用或条件语句中,编译器会抛出“ does not allow precision in this context”的错误消息。
这是因为GLSL ES只允许在变量声明中使用precision,而不能将其用于控制流语句或函数调用等其他地方。如果您需要在GLSL ES中设置变量的精度,您可以在变量声明中使用precision关键字:
```
precision highp float;
uniform highp vec4 u_color;
```
如果您需要在GLSL ES中使用高精度运算,您可以使用inout参数或函数返回值的方式进行传递。例如,以下是一个使用inout参数进行高精度加法的示例:
```
precision highp float;
void add(inout highp float x, highp float y) {
x = x + y;
}
void main() {
highp float a = 0.1;
highp float b = 0.2;
add(a, b);
gl_FragColor = vec4(a, 0.0, 0.0, 1.0);
}
```
在该示例中,我们使用inout参数引用变量x,可以在函数内部修改它的值,从而高精度运算。1027b8d030e82e1ae0909871glsl 避免shader优化
在GLSL中,如果您需要避免编译器优化您的着色器(shader),您可以使用以下技术:
1. 使用内联汇编:您可以使用内联汇编为某些计算提供汇编语言实现,从而强制编译器不要优化掉这些计算。这需要您对汇编语言有一定的了解,并且不是所有的GLSL实现都支持内联汇编。
以下是使用内联汇编计算平方根的示例:
```
float fastSqrt(float x) {
float result;
asm("sqrt.s %0, %1\n" : "=f"(result) : "f"(x));
return result;
}
```
2. 避免短路:在GLSL中,布尔运算符(&&和||)可能会有短路行为。编译器可能会将短路表达式的计算优化为只计算必要的部分。因此,如果您希望强制编译器计算整个表达式,请使用按位逻辑运算符(&和|)。
以下是一个避免短路优化的示例:
```
// 使用逻辑或运算符的代码:
if (a || b) { ... }
// 避免短路优化的代码:
if (a | b) { ... }
```
3. 使用volatile关键字:使用volatile关键字声明变量可以告诉编译器不要优化掉这个变量,即使看起来它似乎可以被优化掉。
以下是使用volatile关键字避免优化的示例:
```
volatile float x = ...;
x = x * 2.0 + 1.0;
```
4. 使用#define定义常量:在GLSL中,您可以使用#define指令定义常量。将常量定义为字面量值可以避免编译器进一步优化它们。
以下是定义常量的示例:
```
#define PI 3.14159265358979323846
float computeCircumference(float r) {
return 2.0 * PI * r;
}
```
请注意,这些方法并不总是有效,并且可能会降低代码的性能。在使用它们之前,请确保了解它们的潜在影响,并根据情况进行选择。8b2176a5a14b4e96b71fb8f6normalize是怎么计算的
normalize(归一化)是一个用于将向量标准化的操作。在3D图形编程中,向量通常用于表示具有方向和大小的量,例如平面上的速度、空间中的位置等。但是,为了在计算中方便使用向量,我们通常将其标准化,即使其大小(向量的长度或模)等于1。
向量在3D空间中的标准化即为其沿着该向量的长度为1。标准化操作的公式为:
```
normalized vector = vector / ||vector||
```
其中,vector表示原始向量,||vector||表示该向量的长度或模,即:
```
||vector|| = sqrt(x^2 + y^2 + z^2)
```
其中x、y和z是向量的分量。
normalize函数在GLSL ES中的定义如下:
```
vec3 normalize(vec3 x);
```
它接受一个vec3类型的向量作为输入参数,并返回其标准化版本。normalize函数的实现如下:
```
vec3 normalize(vec3 x) {
float len = length(x);
if (len < 1e-6) {
return vec3(0.0, 0.0, 0.0);
} else {
return x / len;
}
}
```
在该实现中,normalize函数首先计算向量的长度并将其存储在变量len中。如果向量的长度小于1e-6(阈值),则该函数返回一个长度为零的向量,否则,它将向量除以其长度并返回其标准化版本。
normalize函数还可能用于许多其他操作中,例如计算向量的点积、计算光线与表面法线之间的角度等。通常情况下,将向量标准化是非常有用的,因为它可以将向量方便地用于各种数学计算和3D图形应用程序中。dd791a7a61f29aa05dc75a82gles的normalize不会判断len < 1e-6吗
在GLSL ES中,normalize函数通常不会自动判断向量的长度是否小于一个特定的阈值。取而代之的是,开发者需要通过代码显式地处理长度为零的情况。
如果规范化一个长度为零的向量,将会导致 undefined behavior,即无法确定的行为。此时,计算得到的向量分量都是NaN(not a number)。如果这种NaN向量被用于后续的计算中,可能会导致错误的结果。因此,检测长度是否为零并在需要时避免规范化将是一个好习惯。
在实际开发中,常用的方法是使用一个很小的常数而不是1e-6来代替判断长度是否小于零的情况。例如,常用的阈值是1e-5或1e-6,但是具体的值取决于应用程序的需要。以下是一个使用1e-5的例子:
```
vec3 normalize(vec3 v) {
float len = length(v);
if (len > 1e-5) {
return v / len;
} else {
return vec3(0.0, 0.0, 0.0);
}
}
```
在该实现中,如果向量的长度小于1e-5,则返回一个长度为零的向量,否则返回规范化后的向量。通过使用这种设计,可以确保向量不会被错误地标准化。9e4a86f1e0e4bc3e1d89ea5f我能看gles的nornalize源码吗
由于OpenGL ES是一种标准而不是一种具体的实现,因此normalize函数的具体实现可能因不同的GPU和硬件而异,也可能因不同版本的GLSL ES而异。 normalize函数的源码通常是由GLSL编译器和图形驱动程序提供的。因此,由于不同的OpenGL ES实现使用不同的编译器和驱动程序,所以无法保证它们所有的源代码都是开放的或公开的。 然而,您仍然可以查看GLSL ES语言规范以了解normalize函数的工作原理和行为。该规范可从Khronos Group的网站上免费下载,并提供有关GLSL ES的详细信息和指导。此外,许多开源OpenGL ES库和应用程序提供了GLSL代码示例,您可以从中了解normalize函数的实现和用法。
