SI_CoordinateSystem

Specifies the coordinate system in which transformations are expressed. This template allows game developers to express data in any coordinate system.

Limitations

If an XSI file contains this template, SOFTIMAGE|XSI ignores it.

Description

handRotation

int

Specifies the coordinate system:

0 = left-handed (D3D, PlayStation)

1 = right-handed (SOFTIMAGE|3D, Nintendo)

uAxis

int

Orientation of the U axis for texture coordinates:

0 = right (all)

1 = left

vAxis

int

Orientation of the V axis for texture coordinates:

0 = down (D3D, Nintendo, PlayStation)

1 = up (SOFTIMAGE|3D)

xAxis

int

Orientation of the X axis:

0 = right (all)

1 = left

2 = up

3 = down

4 = in

5 = out

yAxis

int

Orientation of the Y axis:

0 = right

1 = left

2 = up (SOFTIMAGE|3D, D3D, Nintendo)

3 = down (PlayStation)

4 = in

5 = out

zAxis

int

Orientation of the Z axis:

0 = right

1 = left

2 = up

3 = down

4 = in (D3D, PlayStation)

5 = out (SOFTIMAGE|3D, Nintendo)

 

Only SOFTIMAGE|3D-style coordinates are supported by the XSI Export and XSI Import plug-in.

Example

SI_CoordinateSystem 
{
   1,  // right-handed rotation 
   0,  // U axis goes right 
   1,  // V axis goes up 
   0,  // X axis goes right 
   2,  // Y axis goes up 
   5,  // Z axis goes out 
}
