Class: GlimR::Model

Inherits:
SceneObject show all
Defined in:
lib/glimr/renderer/model.rb

Overview

A Model is a convenience SceneObject that has its own transform, material, texture, shader, and geometry.

The state nodes are attached to the Model after super initialization and form a five-node subtree ordered like this (from top to bottom): transform - material - texture - shader - geometry.

Model delegates many accessors to the corresponding state nodes

Example:

m = Model.new
m.texture.load('foo.jpg')
m.position = [10, 20, 30]
m.texcoords = make texcoords
m.vertices = make vertices
