but i want a do i by a GLSL shader
im a newbie in this scope
Theres like no advantages in doing it in a shader, your better off using glBlend, and it will probley be faster.
yes it's faster but my point is to do some per pixel shading. i have many spotlights casting their beam on flat surfaces like cubes, so per vertex don't fit
