asTextureInfo¶

A node providing the user with a number of potentially useful information for the input texture. Notice that the input texture can be any texture, a 2D or 3D texture. The list of information queried might be extended to include appleseed specific metadata.

Parameters¶

Texture Parameters¶

Texture File: The input texture file.

Outputs¶

Average Color

The average color of the first 3 channels of the texture file.

Average Alpha

The average value of the channel with the A name in the texture file, if it exists.

Resolution

A vector containing the X and Y resolution in its first two components, or the X, Y and Z resolution in the case of input 3D texture file.

Channels

The total number of channels in the input texture file.

Subimages

The number of subimages in the texture file. In the EXR case, this refers to the number of additional channels.

Texture Type

Returns the type of the texture file, with the following strings according to the input type

Plain Texture

Shadow

Environment

Volume Texture

Texture Format

The texture format of the input file, differentiating between the format of the fundamental texture types. The return strings can take the following values

Plain Texture

Shadow

CubeFace Shadow

Volume Shadow

CubeFace Environment

LatLong Environment

Volume Texture

Data Window Minimum

A vector containing the minimum X and Y values of the pixel data window of the input texture, in the case of a 2D texture file. And the minimum X, Y and Z values of the pixel data window in the case of a 3D texture file.

Data Window Maximum

A vector containing the maximum X and Y values of the pixel data window of the input texture, in the case of a 2D texture file. And the maximum X, Y and Z values of the pixel data window in the case of a 3D texture file.

Display Window Minimum

A vector containing the minimum X and Y values of the full window of the image, in the case of a 2D texture file, and the minimum X, Y and Z values in the case of a 3D texture file.

Display Window Maximum

A vector containing the maximum X and Y values of the full window of the image, in the case of a 2D texture file, and the maximum X, Y and Z values in the case of a 3D texture file.

World To Camera Matrix

When the input texture is a rendered image, this parameter provides the world to camera transformation matrix used.

World To Screen Matrix

When the input texture is a rendered image, this parameter provides the matrix that transforms points from world space into screen space - a 2D coordinate system where the x and y values are in [-1,1] range.
