如何为已编译的OpenGL列表进行纹理映射? [英] How to do Texture mapping for Compiled OpenGL List?

问题描述

我希望将Texture应用于已经编译的OpenGL List.
是否可以将纹理应用于GL列表?请让我知道该怎么做.
我的OpenGL列表包含TRIANGLE STRIPS(使用gl.Normal3d和gl.Vertex3d定义)

通常，我的代码将生成如下的GL列表.我要在此列表中应用一些纹理.

I am looking to apply Texture to an already compiled OpenGL List.
Is it possible to apply texture to a GL List? Please let me know how to do it.
My OpenGL list contains TRIANGLE STRIPS (defined with gl.Normal3d & gl.Vertex3d)

Typically my code would be generating a GL List as below. To this List I want to apply some texture.

gl.NewList(GLListTag, gl.COMPILE);
 {
   gl.Begin(gl.TRIANGLE_STRIP);
   for (int i = 0; i< PointsCount; i++)
  {
 
   gl.Normal3d(x,y,z)
   gl.Vertex3d(a,b,c)
   }
   gl.End();
}
gl.EndList();

注意:我已经在Graphics讨论区论坛中提出了相同的问题

Note: I have already asked the same question in the Graphics discussion forum

推荐答案

您需要在此处设置纹理坐标(如果我记得正确的话，请使用gl.TexCoords).

You need to set the texture coordinates (using gl.TexCoords if I remember right) at the same time as you set the vertex normal and location.

gl.NewList(GLListTag, gl.COMPILE);
 {
   gl.Begin(gl.TRIANGLE_STRIP);
   for (int i = 0; i< PointsCount; i++)
  {
   gl.TexCoord2f(u, v); // Texture coordinate of the vertex.
   gl.Normal3d(x,y,z)
   gl.Vertex3d(a,b,c)
   }
   gl.End();
}
gl.EndList();
