Texture coordinates

This page describes the types of texture coordinates used with CreativeStudio and how to tile them.

For details on tiling, see the separate document Introduction to CTR Graphics.

Texture Coordinates

With texture coordinates, the bottom left corner is taken as the origin of the texture image. The positive direction for the U-coordinate is toward the right and the positive direction for the V-coordinate is toward the top.

Texture Coordinate System Selection

CreativeStudio can be used to switch texture coordinate calculations to match any of the following three 3D graphics tools: Maya, Softimage, and 3ds Max.

When editing texture coordinates under CreativeStudio, select the easiest coordinate system to use.

Texture Coordinate System (Maya)

The method of calculating texture coordinates is the same as with Maya.

Item, Value and Value Display Result Description
Scale Maya and Softimage Scale Scales the bottom left of the image to the center.
Rotation Maya and 3dsMax Rotation Rotates the exact center of the image clockwise around the center.
Jump Maya Movement Moves along the top, bottom, left, and right of the image.

Texture Coordinate System (Softimage)

The method of calculating texture coordinates is the same as with Softimage.

Item and Value Display Result Description
Scale Maya and Softimage Scale Scales the bottom left of the image to the center.
Rotation Softimage Rotation Rotates the bottom left of the image counterclockwise around the center.
Jump Softimage Movement Moves up, down, left, and right.

Texture Coordinate System (3ds Max)

The method of calculating texture coordinates is the same as with 3ds Max.

Note: This is the only coordinate system that can scale and rotate around the texture center.

Item and Value Display Result Description
Scale 3dsMax Scale Scales the exact center of the image to the center.
Rotation Maya and 3dsMax Rotation Rotates the exact center of the image clockwise around the center.
Jump 3dsMax Movement Moves up, down, left, and right.

Texture Tiling

Methods of tiling include repeating textures, and making separate settings in the vertical and horizontal directions for shifting textures slightly upon each repetition, and processing the edges of the image.

There are four tiling methods that can be selected under CreativeStudio: repeat, mirror, clamp, and border clamp.

This section describes the graphics processed image for each tiling method based on the texture given below.

Sample Texture

Repeat

Repeats the texture unchanged.

The following image repeats in the vertical and horizontal directions.

Repeat

Mirror

Repeatedly mirrors the texture.

The following image mirrors the texture in the vertical and horizontal directions.

Mirror

Clamp

Extends the color at the edge of a texture.

The following image clamps the texture in the vertical and horizontal directions.

Clamp

Clamp borders

The following image fills the region outside the texture area with the specified border color.

The following image border clamps the texture in the vertical and horizontal directions.
