Enumeration Type Documentation

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 140 of file DrawModes.hh.

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 113 of file DrawModes.hh.

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 165 of file DrawModes.hh.

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 124 of file DrawModes.hh.

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 153 of file DrawModes.hh.

Function Documentation

ACGDLLEXPORT const DrawMode & ACG::SceneGraph::DrawModes::addDrawMode	(	const std::string &	_name,
		bool	_propertyBased = `false`
	)

Add a custom DrawMode.

The id of the new draw mode is returned. If it already exists, the id of the existing one is returned.

Property based draw modes consist of various flags, which define which primitives and additional information are send to the gpu.

Parameters

_name	Name of the draw mode to add
_propertyBased	If set to true a property based draw mode is created.

Returns: Id of the new draw mode

Definition at line 771 of file DrawModes.cc.

ACGDLLEXPORT const DrawMode & ACG::SceneGraph::DrawModes::addDrawMode	(	const std::string &	_name,
		const DrawModeProperties &	_properties
	)

Add a custom property based DrawMode.

The id of the new draw mode is returned. If it already exists, the id of the existing one is returned.

Note: If the DrawMode already exists, the properties will be applied to the existing mode!!

Property based draw modes consist of various flags, which define which primitives and additional information are send to the gpu.

Parameters

_name	Name of the draw mode to add
_properties	Properties of the drawmode

Returns: Id of the new draw mode

Definition at line 793 of file DrawModes.cc.

ACGDLLEXPORT bool ACG::SceneGraph::DrawModes::drawModeExists ( const std::string & _name )

Check if the given draw mode exists.

Definition at line 830 of file DrawModes.cc.

ACGDLLEXPORT const DrawMode & ACG::SceneGraph::DrawModes::getDrawMode ( const std::string & _name )

Get a custom DrawMode.

The id of the draw mode is returned or if it does not exist, DrawMode::NONE is returned.

Parameters

_name Name of the DrawMode

Returns: Id of the draw mode or DrawModes::NONE

Definition at line 813 of file DrawModes.cc.

ACGDLLEXPORT void ACG::SceneGraph::DrawModes::initializeDefaultDrawModes ( void )

Initialize the default modes. This function has to be called at least once at application startup.

Definition at line 645 of file DrawModes.cc.

Variable Documentation

ACGDLLEXPORT DrawMode ACG::SceneGraph::DrawModes::SOLID_SHADER = ModeFlagSet(1) << 26

drawing is controlled by shaders ( Use shadernodes to set them before the actual object to render)
