Package jgl.context.render

Class gl_render

java.lang.Object
jgl.context.render.gl_render
Direct Known Subclasses:
gl_depth, gl_select_render
public class gl_render extends Object
gl_render is the basic rendering class of JavaGL 2.1. The most important method is draw_line(gl_vertex, gl_vertex) which paints the pixel between 2 2D points. The third dimension of the vertex represents the depth of the pixel. Note that considering depth for drawing a pixel is made in gl_depth (a subclass of gl_render)
