Detailed Description

This implements everything which is the same for all render modes using raycasting, but has different data. This class is abstract due to the lack of a render-method.

See also:

Member Function Documentation

virtual void VolVis::VolumeRendering::RaycastRendering::prepareForRender

(

bool

viewChanged

)

[inline, virtual]

Uses the raycasting object for creating the direction cubes (if they need to be updated).

Parameters:

viewChanged

if true, the direction cubes are updated in any case.

Reimplemented from VolVis::VolumeRendering::Rendering.

void VolVis::VolumeRendering::RaycastRendering::setStepSize

(

double

stepSize

)

[inline]

Defines the step size of the raycasting. In which intervals is the volume sampled by a casted ray.

Parameters:

stepSize

interval for sampling in raycasting

Field Documentation

Raycasting* VolVis::VolumeRendering::RaycastRendering::m_pRaycasting [protected]

The raycasting object contains data and code which is the same for all render modes. The same object can be bound to all raycasting render modes.

Shader::ShaderObject* VolVis::VolumeRendering::RaycastRendering::m_pRaycastShader [protected]

This shader object renders the direction cubes.
