Hey,

I have noticed that when one draws a triangle either with shaders or out of vertices in JOGL, the triangle comes out sort of big, and one has to apply scaling to make it smaller.

Isn't there a way where one can take the dimensions of the viewport and build a triangle(s) or a rectangle(s) the size of 50 pixels wide versus a 100 pixels wide triangle or rectangle?

For instance, I dont' want to have to scale down any of the geometry to make them look one bigger or smaller then the next one.

I want the physical distance I have from one vertex to the next to define the shape and size of the geometry. I don't want JOGL to produce that for me. Does this has to do with the perspective matrix?

Any ideas.

Thanks.
