Enumeration Type Documentation

◆ DrawModeColorSource

enum ACG::SceneGraph::DrawModes::DrawModeColorSource

Source of Primitive Colors.

This is interpreted as a per vertex diffuse and ambient color and multiplied with the material diffuse/ambient colors.

Enumerator
COLOR_NONE	Use material colors only
COLOR_PER_VERTEX	Load per vertex colors and modulate with material color
COLOR_PER_EDGE	Load per edge colors and modulate with material color
COLOR_PER_HALFEDGE	Load per halfedge colors and modulate with material color
COLOR_PER_FACE	Load per face colors and modulate with material color

Definition at line 134 of file DrawModes.hh.

◆ DrawModeLightStage

enum ACG::SceneGraph::DrawModes::DrawModeLightStage

Lighting stage of a mesh: unlit, smooth, phong.

Don't confuse this with the interpolation mode of vertex attributes. This only says where to apply lighting, and nothing else.

Instead the interpolation mode is customizable for each attribute, making DrawModeProperties more flexible.

flat shading can be achieved by using LIGHTSTAGE_SMOOTH and setting the normal source to NORMAL_PER_FACE

Enumerator
LIGHTSTAGE_UNLIT	No lighting, normals may be used by user defined shaders
LIGHTSTAGE_SMOOTH	Perform lighting in vertex shader
LIGHTSTAGE_PHONG	Perform lighting in fragment shader

Definition at line 107 of file DrawModes.hh.

◆ DrawModeNormalSource

enum ACG::SceneGraph::DrawModes::DrawModeNormalSource

Source of Normals.

This must be specified if lighting is enabled.

Enumerator
NORMAL_NONE	Disable lighting
NORMAL_PER_VERTEX	Use per vertex normals
NORMAL_PER_HALFEDGE	Use per halfedge normals
NORMAL_PER_FACE	Use per face normals Note per face is implicitly used in SHADE_FLAT mode

Definition at line 159 of file DrawModes.hh.

◆ DrawModePrimitive

enum ACG::SceneGraph::DrawModes::DrawModePrimitive

Primitive mode of a mesh.

Example: PRIMITIVE_EDGE on a polygon mesh renders only edges of the mesh.

Definition at line 118 of file DrawModes.hh.

◆ DrawModeTexCoordSource

enum ACG::SceneGraph::DrawModes::DrawModeTexCoordSource

Source of Texture Coordinates.

This must be specified for a textured draw.

Enumerator
TEXCOORD_NONE	Disable texture mapping
TEXCOORD_PER_VERTEX	Use per vertex texcoords for texture mapping
TEXCOORD_PER_HALFEDGE	Use per halfedge texcoords for texture mapping

Definition at line 147 of file DrawModes.hh.
