Hello Janna,
If you use a shader program you'll have to bind the attributes to the
program:
const std::string name="v_tangent"
program->addBindAttribLocation(name, index);
Then in the vertex shader you can access the attribute via:
attribute vec3 v_tangent;

Hi,
I am working on optimizing existing code for height field. I've enabled VBO for
height field geometry which seems to make draw time faster however it seems can
not retrieve vertex attribute data in the vertex shader anymore.
Is there a special way of using VBO with geometry which has additional vertex
attribute data set up? Data is set up on vertex attribute array with the index
15.
Thank you!
Cheers,
Janna
