Constructor & Destructor Documentation

VolVis::VolumeRendering::FirstHit::FirstHit

(

Raycasting *

raycasting

)

Constructor. Binds the raycasting object and loads the needed shaders.

Parameters:

raycasting

this implements the raycasting algorithm

Member Function Documentation

void VolVis::VolumeRendering::FirstHit::enablePhong

(

bool

enable

)

Enables or disables the phong reflection model. If enabled, the reflection is calculated according to the reflection parameters and the light source defined in the Raycasting object.

Parameters:

enable

if true, the phong reflection model is enabled.

void VolVis::VolumeRendering::FirstHit::render

(

)

[virtual]

Updates shader parameters and renders an image plane. Raycasting is done within a shader.

Implements VolVis::VolumeRendering::Rendering.

void VolVis::VolumeRendering::FirstHit::setThreshold

(

float

t

)

Defines the threshold for the voxels which should be visible. The first voxel in front-to-back-order which has a higher value than this threshold is selected.

Parameters:

t

defines the visibility threshold.
