Constructor & Destructor Documentation

U4DRenderGeometry()

U4DEngine::U4DRenderGeometry::U4DRenderGeometry

(

U4DBoundingVolume *

uU4DGeometricObject

)

Constructor for class.

Sets the bounding volume the class will manate

Member Function Documentation

alignedAttributeData()

void U4DEngine::U4DRenderGeometry::alignedAttributeData

(

)

Aligns attribute data.

Aligns the vertices before sending them to the GPU

clearModelAttributeData()

void U4DEngine::U4DRenderGeometry::clearModelAttributeData ( )

virtual

Clears the attribute container.

clears vertices containers

Reimplemented from U4DEngine::U4DRenderEntity.

loadMTLAdditionalInformation()

void U4DEngine::U4DRenderGeometry::loadMTLAdditionalInformation ( )

virtual

Loads additional information into buffer.

loads the color of the geometrical shape

Reimplemented from U4DEngine::U4DRenderEntity.

loadMTLBuffer()

bool U4DEngine::U4DRenderGeometry::loadMTLBuffer ( )

virtual

Loads the attributes and Uniform data.

It prepares the attribute data so that it is aligned. It then loads the attributes into a buffer. It also loads uniform data into a buffer

Returns

True if loading is successful

Reimplemented from U4DEngine::U4DRenderEntity.

modifyRenderingInformation()

void U4DEngine::U4DRenderGeometry::modifyRenderingInformation ( )

virtual

Modifies geometry rendering data if required.

This method is called by the U4DBoundingVolume class. If the attribute container size changes, it loads a new set of attributes.

Reimplemented from U4DEngine::U4DRenderEntity.

render()

void U4DEngine::U4DRenderGeometry::render ( id< MTLRenderCommandEncoder >  uRenderEncoder )

virtual

Renders the current entity.

Updates the space matrix, any rendering flags, bones and shadows properties. It encodes the pipeline, buffers and issues the draw command

Parameters

uRenderEncoder

Metal encoder object for the current entity

Reimplemented from U4DEngine::U4DRenderEntity.

setGeometryLineColor()

void U4DEngine::U4DRenderGeometry::setGeometryLineColor ( U4DVector4n &  uGeometryLineColor )

virtual

Sets the color for the geometry.

Sets the line color used for rendering the geometrical figure

Parameters

uGeometryLineColor

line color

Reimplemented from U4DEngine::U4DRenderEntity.

updateRenderingInformation()

void U4DEngine::U4DRenderGeometry::updateRenderingInformation ( )

virtual

Updates the geometry rendering data.

This method is called by the geometry U4DBoundingVolume class whenever the data changes

Reimplemented from U4DEngine::U4DRenderEntity.

updateSpaceUniforms()

void U4DEngine::U4DRenderGeometry::updateSpaceUniforms ( )

virtual

Updates the space matrix of the entity.

Updates the model space matrix of the entity by computing the world, view and perspective space matrix

Reimplemented from U4DEngine::U4DRenderEntity.
