Pixar’s RenderMan has a brickmap file format similar to Houdini’s i3d (Image 3D) files. The Brick Map Generator ROP allows you to convert Houdini volume primitives into Pixar brickmap files. The Brick Map Generator ROP is a wrapper around the
hbrickmap command line tool.
Begins the render with the last render control settings.
Opens the render control dialog to allow adjustments of the render parameters before rendering.
Render with Take
Uses the settings in a particular take while rendering. Choose Current to use the current take when rendering.
Valid frame range
Limits the rendering of frames, when set to Render frame range or Render frame range only.
Render any frame
Allow the renderer to render any and all frames.
Render frame range
Only render the frames in the range set below, but allow the renderer to render other frames if they are referenced by in-range frames.
Render frame range only (strict)
Only render the frames in the range set below, and don’t allow the renderer to render other frames, even if they are referenced by in-range frames.
Specifies the range of frames to render (start frame, end frame, and increment). All values may be floating point values. The range is inclusive.
These parameters determine the values of the local variables for the output driver.
Name of the brickmap to generate.
What type of source geometry to convert to a brickmap file. This can be either and
.i3d file on disk, a disk file containing volume primitives, or a SOP containing volume primitives.
Source i3d file to convert to a brickmap file.
Source geometry file to convert to a brickmap file.
Volume geometry SOP to to convert to a brickmap file.
Point Cloud File
Store the intermediate Point Cloud file (in Pixar’s .ptc format).
The filter used when evaluating volume primitives.
Volume Filter Width
The filter width used when evaluating volume primitives.
Create Os from Density
Automatically create the Os channel in the brickmap based on the density channel in the volume primitive/i3d file.
