I'm trying to change the aspect ratio of my jit.gl.render.

I tried jit.gl.sketch with glperspective but nothing changes. Is that a mistake in the documentation? should it be gluperspective?

With gluperspective something happens but I don't understand the result. I expected it to be gluperspective fovy aspect zNear zFar.

I used values like gluperspective 45. 1. 0.1 10. but the results look somehow drastic. Like wrapped around. I can't figure out the right values. What's wrong with that. Is there any other possibility to set the aspect ratio?

Try this patch. The problem is most likely you're not changing the

matrixmode to projection and/or you're not loading the identity matrix

before calling gluperspective. If you read the spec on gluperspective

carefully, you'll see that it creates a matrix and then does the

equivalent of glmultmatrix on what is already loaded. This is a

Thanks a lot wes. What do you mean with spec? The redbook?

I mean the manpage for the function which can be found in the redbook

or on the opengl site. You can also do a google search
