Constructor & Destructor Documentation

◆ VoxelGrobShader()

OGF::VoxelGrobShader::VoxelGrobShader ( VoxelGrob * grob )

VoxelGrobShader constructor.

Parameters

[in] grob a pointer to the VoxelGrob this shader is attached to

Member Function Documentation

◆ blink()

void OGF::VoxelGrobShader::blink ( )

overridevirtual

Draws the current object several times, while chaning the value of one graphic attribute (e.g. mesh on/off), to draw attentin towards it.

This function is used if object highlighting is activated.

Reimplemented from OGF::Shader.

Reimplemented in OGF::PlainVoxelGrobShader.

◆ draw()

void OGF::VoxelGrobShader::draw ( )

overridevirtual

Draws the Grob.

The Grob is the one that was passed to the constructor of this Shader.

Reimplemented from OGF::Shader.

Reimplemented in OGF::PlainVoxelGrobShader.

◆ pick_object()

void OGF::VoxelGrobShader::pick_object ( index_t object_id )

overridevirtual

Draws the Grob in picking mode.

In picking mode, drawing is replaced by filling the pixel values with 32 bits ids, while ZBuffer is still activated. Thus, after drawing the whole scene, one can find for a given pixel which object is visible by reading the 32 bit id encoded in the pixel color.

Parameters

[in] object_id all the pixels covered by the object will be assigned this value

Implements OGF::Shader.

Reimplemented in OGF::PlainVoxelGrobShader.

◆ voxel_grob()

VoxelGrob* OGF::VoxelGrobShader::voxel_grob ( ) const

inlineprotected

Gets the VoxelGrob.

Returns: a pointer to the VoxelGrob this shader is attached to
