Cube Map

[ Main Manual Page ]


CubeMap (3Cu)

The CubeMap tool creates texture maps using seperate images for each face of the cube. It can also extract the individual faces of the cube from a single image containing an unfolded cube in the vertical or horizontal cross layouts.

A cube map is produced by mounting 6 cameras at 90 degrees angle of views to point up, down, left, right, front, and back.

The tool provides options to set the reference coordinate system and rotation for the resulting texture map. The CubeMap tool is typically used to produce environment maps for distant areas (such as skies or horizons) or reflection and refraction maps.

External Inputs

CubeMap.CrossImage
[ white, required ] This input is only visible when the tool is set to the Vertical Cross or Horizontal Cross orientation. It expects a 2D image.
CubeMap.[DIRECTION]
[ white, required ] These six inputs are only visible when the tool is set to the Separate Images orientation mode. Each input expects an image aligned to match the left, right, up, down, front and back faces.





Controls


Orientation

This multibutton control tells the tool which type of input to expect for the cubemap texture. Valid options are:

Separate Images
This option exposes six inputs on the tool tile, one for each face of the cube. If the separate images are not square or not of the same size, they will be rescaled into the largest 1:1 image that can contain all of them.
Vertical Cross
This option exposes a single input on the tool tile. The image should be a unwrapped texture of a cube containing all the faces organized into a vertical cross formation, where the height is larger than the width. If the image aspect of the cross image is not 3:4 the cubemap tool will crop it down so that matches the appropriate aspect ratio.
Horizontal Cross
This option exposes a single input on the tool tile. The image should be a unwrapped texture of a cube containing all the faces organized into a horizontal cross formation, where the width is larger than the height. If the image aspect of the cross image is not 4:3 the cubemap tool will crop it down so that matches the appropriate aspect ratio.


Coordinate System

This multibutton control sets the coordinate system used when converting the image into a texture.

Model
This option orients the texture along the object local co-ordinate system.
World
This option orients the resulting texture using the global or world coordinate system.
Eye
This option aligns the texture map to the coordinate system of the camera or viewer.


Warn about bad dimensions

Selecting this checkbox will print a warning message into the console if the dimensions of the image provided does not meet the requirements of the selected orientation mode.


Material ID

This slider sets the numeric identifier assigned to this material. This value will be rendered into the MatID auxiliary channel if the according option is enabled in the renderer.
