GL.TexCoord3 纹理坐标3
static function TexCoord3 (x : float, y : float, z : float) : void
Description描述
Sets current texture coordinate (x,y,z) for all texture units.
设置纹理(x,y,z)坐标对于所有的纹理单元。
In OpenGL this matches glMultiTexCoord for all texture units or glTexCoord when no multi-texturing is available. On other graphics APIs the same functionality is emulated.
这个函数和OpenGL中的glMultiTexCoord(多重纹理),glTexCoord函数一样。其它的图形API也有对应的功能。
The Z component is used only when:
1. You access a cubemap (which you access with a vector coordinate, hence x,y & z).
2. You do "projective texturing", where the X & Y coordinates are divided by Z to get the final coordinate. This would be mostly useful for water reflections and similar things.
Z坐标用在以下情况:
1. 六面体纹理。
2. 投影纹理。Z有X,Y坐标得到。例如水面倒射效果。
This function can only be called between GL.Begin and GL.End functions.
