Hi, I am currently working on a project requires gpu instancing. I worked out a way to do the instancing with vec4 as position attribute in. However, in the real case, instances need to be scaled/rotated/translated. Now, I want to send the transform matrix as an attribute to the shader. Normally, general opengl uses glVertexAttribPointer with offset and glVertexAttribDivisor to sperate mat4 to vec4 then pass to the shader. However, I don't find the replacement function to do the offset data structure pass. Could someone enlighten me about it, please?
thanks very much! ... Thank you!
