The Stereo Camera Template (stereocam) is a native operator type in Houdini. Houdini viewport recognizes the stereocam type and uses the anaglyph composition mode for displaying the scene.
The left menu chooses the order in which transforms are applied (for example, scale, then rotate, then translate). This can change the position and orientation of the object, in the same way that going a block and turning east takes you to a different place than turning east and then going a block.
The right menu chooses the order in which to rotate around the X, Y, and Z axes. Certain orders can make character joint transforms easier to use, depending on the character.
Translation along XYZ axes.
Degrees rotation about XYZ axes.
Local origin of the object. See also setting the pivot point .
This menu contains options for manipulating the pre-transform values. The pre-transform is an internal transform that is applied prior to the regular transform parameters. This allows you to change the frame of reference for the translate, rotate, scale parameter values below without changing the overall transform.
This reverts the translate, rotate, scale parameters to their default values while maintaining the same overall transform.
This sets the translate parameter to (0, 0, 0) while maintaining the same overall transform.
This sets the rotate parameter to (0, 0, 0) while maintaining the same overall transform.
This sets the scale parameter to (1, 1, 1) while maintaining the same overall transform.
This removes the pre-transform by setting the translate, rotate, and scale parameters in order to maintain the same overall transform. Note that if there were shears in the pre-transform, it can not be completely removed.
This completely removes the pre-transform without changing any parameters. This will change the overall transform of the object if there are any non-default values in the translate, rotate, and scale parameters.
Keep Position When Parenting
When the object is re-parented, maintain its current world position by changing the object’s transform parameters.
When the object is being transformed, maintain the current world transforms of its children by changing their transform parameters.
Enable Constraints Network on the object.
Path to a CHOP Constraints Network. See also creating constraints.
You can you use the Constraints drop down button to activate one of the Constraints Shelf Tool. If you do so, the first pick session is filled automatically by nodes selected in the parameter panel.
Specify the left and right view points.
Instructs the Mantra render node to use the left and right cameras for rendering.
By default the Left Camera and Right Camera refer to the Stereo Camera Template node itself, thus producing identical images for the left and right channels.
Whether or not this object is displayed in the viewport and rendered. Turn on the checkbox to have Houdini use this parameter, then set the value to 0 to hide the object in the viewport and not render it, or 1 to show and render the object. If the checkbox is off, Houdini ignores the value.
Set Wireframe Color
Use the specified wireframe color
The display color of the object
Viewport Selecting Enabled
Object is capable of being picked in the viewport.
Script to run when the object is picked in the viewport. See select scripts .
Cache Object Transform
Caches object transforms once Houdini calculates them. This is especially useful for objects whose world space position is expensive to calculate (such as Sticky objects), and objects at the end of long parenting chains (such as Bones). This option is turned on by default for Sticky and Bone objects.
See the OBJ Caching section of the Houdini Preferences window for how to control the size of the object transform cache.
Scales the viewport geometry. This parameter is only for display purposes.
The output resolution in pixels. Standard presets are available via the pull down menu to the right of the parameter.
Pixel aspect ratio
The pixel aspect ratio of the output image.
Type of camera projection used for rendering.
This simulates the classic pinhole camera where camera rays emanate from a common camera origin through a flat camera plane.
This uses parallel camera rays that are orthogonal to the (flat) camera plane. The width of the view volume is determined by the Ortho Width parameter below.
This projection uses a spherical camera plane for rendering.
This projection uses a cylindrical camera plane for rendering.
Selecting Polar or Cylindrical will automatically switch the Rendering Engine (on the output driver) to Ray Tracing, as it is impossible to render a polar or cylindrical projection with micropolygon rendering.
Camera focal length (zoom).
The units used for the focal length.
Width of the visible field.
Width of orthographic view volume when using Projection is set to Orthographic.
Position of near clipping plane.
Position of far clipping plane.
Screen Window X/Y
Define the center of the window during the rendering process.
Screen Window Size
Scale for expanding the cropped area specified by the Crop parameters.
The portion of the frame interval that the camera shutter is
open. Used to determine motion blur.
The lens focal distance and distance from the camera at which objects will be in focus. This is only used when rendering using depth of field. Objects outside this distance will be blurred.
Lens fstop. This is only used when rendering using depth of field. Determines blurriness of depth of field effects.
Filter kernel used in depth of field rendering.
Use a gaussian filter kernel (highest quality)
Use a box filter kernal
Do not filter
