Title: 2D Primitives
Post by: Melssj5 on May 15, 2006, 01:18:41 am

Hi, is ti posible to draw 2d primitives like Lines, circles, rectangles and things like that???? I need them for a homework and all my classmates are asking for a engine to do that.

This is probably not the best way, but you can use Primitives.getPlane() to create an Object3D plane and use setTransparency() on it. Then apply a texture that would have a drawing of your 2D shape on it.

seems as java.awt.geom package is the engine you are looking for ;)

I need to work with 2d primitives but in OpenGl. Any possibilities to do it in jpct?

i know almost nothing about open gl but i will most likely go after the Mr.Marbles' approach. java.awt.geom package can help to generate textures on the fly

Generating textures on the fly to do this is suitable if it's all part of a 3d application. But if this is a 2d application, i don't recommend to use jPCT for this at all...it's a 3d engine, not a function plotter.

Ok, thanks. Anyway to draw just a point on a pixel?, I can manually draw the lines.
