a vertex shader consists of two parts: shader function and shader declaration.
顶点着色器包含两个部分:着色器函数和着色器声明。
you can create your vertex shader in two ways (that i know).
创建顶点着色程序你可有两种方法。
now let」s see how these registers and instructions are typically used in the vertex shader alu .
现在让我们来看看在顶点着色运算器中这些寄存器和指令如何被典型的运用。
the following three lines from the vertex shader code determine the absolute offset into the matrix array which is stored as constants.
下列三行顶点着色代码,求出矩阵数组里存储的常量的绝对偏移量。
using vertex shader instructions the polynomial coefficients and spherical harmonics functions can be fast calculated, and then the corresponding irradiance environment maps are also generated.
