IfcBlobTexture

Definition from IAI: An IfcBlobTexture provides a 2-dimensional distribution of the lighting parameters of a surface onto which it is mapped. The texture itself is given as a single binary, representing the content of a pixel format. The file format of the pixel file is given by the RasterFormat attribute and allowable formats are guided by where rule WR41.

> NOTE Toolbox specific implementations of the binary datatype may restrict the maximum length of the binary to capture the binary file content.

For interpretation of the texture nodes see IfcImageTexture definition.

> HISTORY New class in Release IFC2x Edition 3.
