Function Documentation

void fhrt_isoval_adapt ( rendersurf * rtsurf,

uint32_t * voxel,

float * ipos,

float * ifor,

float * iup,

float * istr

)

Generate rays to cover the screen.
A simple adaptive raycasting-scheme is followed here. If the colors of adjacent coarse-grid-scanpoint differ too much, then new rays are cast. This happens "recursively" until either small enough blocks are reached, or the pixels don't differ too much and can therefore be filled with the "unique" color of the 4 adjacents pixels.
Parameters:

rtsurf Pointer to surface to draw to.

voxel Pointer to the 3D dataset.

ipos Pointer to the camera-position.

ifor Pointer to the camera-viewvector.

iup Pointer to the camera-upvector.

istr Pointer to the camera-strafevector.

void fhrt_isoval_fine ( rendersurf * rtsurf,

uint32_t * voxel,

float * ipos,

float * ifor,

float * iup,

float * istr

)

Generate rays to cover the screen.
A ray is generated for every pixel.
Parameters:

rtsurf Pointer to surface to draw to.

voxel Pointer to the 3D dataset.

ipos Pointer to the camera-position.

ifor Pointer to the camera-viewvector.

iup Pointer to the camera-upvector.

istr Pointer to the camera-strafevector.

void fhrt_noip_adapt ( rendersurf * rtsurf,

uint32_t * voxel,

float * ipos,

float * ifor,

float * iup,

float * istr

)

Generate rays to cover the screen.

This happens "recursively" until either small enough blocks are reached, or the pixels don't differ too much and can therefore be filled with the "unique" color of the 4 adjacents pixels.
Parameters:

rtsurf Pointer to surface to draw to.

voxel Pointer to the 3D dataset.

ipos Pointer to the camera-position.

ifor Pointer to the camera-viewvector.

iup Pointer to the camera-upvector.

istr Pointer to the camera-strafevector.

void fhrt_noip_fine ( rendersurf * rtsurf,

uint32_t * voxel,

float * ipos,

float * ifor,

float * iup,

float * istr

)

Generate rays to cover the screen.
A ray is generated for every pixel.
Parameters:

rtsurf Pointer to surface to draw to.

voxel Pointer to the 3D dataset.

ipos Pointer to the camera-position.

ifor Pointer to the camera-viewvector.

iup Pointer to the camera-upvector.

istr Pointer to the camera-strafevector.

void getinput ( void )

Input-handler.
Polls the input-devices. Keyboard, Mouse and Window-manager-events are handled here.

void slice_rt ( rendersurf * rtsurf,

uint32_t * voxel

) [inline]

Render slices by raytracing.

Parameters:

rtsurf Pointer to the memory-area to draw to.

voxel Pointer to the voxel-dataset.
