Need Minimum Textures required for OpenGL -
quick question, minimum amount of textures can bound fragment shader opengl implementation required have?
note: know opengl 1.5, opengl 2.0, , opengl 2.1
opengl 1.x , 2.x require @ least 2 texture units. opengl 3.x , 4.x require @ least 16. current gpus have 32.
you can find values in opengl specification itself, in "implementation dependent values" table. specific value called max_texture_units
in 1.x , 2.x , max_texture_image_units
in 3.x , 4.x.
