Class RenderState

java.lang.Object
  com.threerings.opengl.renderer.state.RenderState

Direct Known Subclasses:

AlphaState, ArrayState, ColorMaskState, ColorState, CullState, DepthState, FogState, LightState, LineState, MaterialState, PointState, PolygonState, ShaderState, StencilState, TextureState, TransformState

public abstract class RenderState
extends Object

The superclass for all render state classes. Each render state class represents a separate aspect of the OpenGL state. Because the renderer relies on referential equality while rendering, the states must not change while rendering is taking place.

Field Summary

static int	ALPHA_STATE The alpha testing/blending state.
static int	ARRAY_STATE The geometry array state.
static int	COLOR_MASK_STATE The color mask state.
static int	COLOR_STATE The draw color state.
static int	CULL_STATE The back-face culling state.
static int	DEPTH_STATE The depth testing/writing state.
static int	FOG_STATE The fog state.
static int	LIGHT_STATE The light state.
static int	LINE_STATE The line state.
static int	MATERIAL_STATE The material state.
static int	POINT_STATE The point state.
static int	POLYGON_STATE The polygon state.
static int	SHADER_STATE The GLSL shader state.
static int	STATE_COUNT The total number of state types.
static int	STENCIL_STATE The stencil state.
static int	TEXTURE_STATE The texture state.
static int	TRANSFORM_STATE The transform state.
