Re: [Factor-talk] OpenGL3.0+

2021-05-22 Thread Ken Causey
First I should be clear that I claim no special knowledge.  I'm more of an
interested observer and occasional dabbler with Factor.

However, a quick grep turned up these areas that may help further at least
in the form of example code:

Re: [Factor-talk] OpenGL3.0+

2021-05-22 Thread George Cherevichenko
There are three lines of the code which I cannot write in Factor

glBufferData(GL_ARRAY_BUFFER, sizeof(vertices), vertices, GL_STATIC_DRAW);
glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 3 * sizeof(GLfloat),
(GLvoid*)0);
 glEnableVertexAttribArray(0);

I wanted to use "with-gl-buffer" or "with-vertex-array" from Factor's
opengl vocabulary. Are there examples of using these commands?
