Class for procedurally genereted geometries, like spheres and cubes.

Constructor & Destructor Documentation

ProceduralGeometry() [1/2]

ProceduralGeometry::ProceduralGeometry	(	glm::mat4	modelMatrix,
		GeometryData &	geometryData,
		std::shared_ptr< Material >	material
	)

Creates a procedural geometry object

Parameters

modelMatrix	The model matrix of the geometry. Transforms geometry from object to world space.
geometryData	Data of the vertices and connectivity. This is used to construct the indexed buffers.
material	Material of the geometry, defining the brdf properties of the geometry.

ProceduralGeometry() [2/2]

ProceduralGeometry::ProceduralGeometry	(	glm::mat4	modelMatrix,
		GeometryData &	geometryData,
		std::shared_ptr< Shader >	shader
	)

Creates a procedural geometry object with standard material values for a given shader.

Parameters

modelMatrix	The model matrix of the geometry. Transforms geometry from object to world space.
geometryData	Data of the vertices and connectivity. This is used to construct the indexed buffers.
shader	Shader that is used to draw. Is used to construct the default material.

[in,out]	geometry	GeometryData to which the sphere will be added.

draw()

void ProceduralGeometry::draw ( glm::mat4  matrix = glm::mat4(1.0f) )

virtual

Function defining how to draw the Geometry.

Parameters

matrix

Defines a transformation from word space to word space. Gets left-multiplied with the model matrix.

Implements Geometry.
