gl_PointCoord always zero
- by Jonathan
I am trying to draw point sprites in OpenGL with a shader but gl_PointCoord is always zero.
Here is my code
Setup:
//Shader creation..(includes glBindAttribLocation(program, ATTRIB_P, "p");)
glEnableVertexAttribArray(ATTRIB_P);
In the rendering loop:
glUseProgram(shader_particles);
float vertices[]={0.0f,0.0f,0.0f};
glEnable(GL_TEXTURE_2D);…
