What's New in IDL 6.4: New Features in IDL 6.4

New IDL Object Methods

The following IDL object classes have new methods in this release. See the following topics in the IDL Reference Guide for complete reference information.

IDLgrImage::ReadFilteredData

This method returns the image data after the application of one or more image filtering IDLgrShader programs to the image.

IDLgrImage::TileDataLoaded

This method returns a boolean value indicating whether the specified tile already has data loaded.

IDLgrPlot::GetVertexAttributeData

This method retrieves the data associated with a named attribute variable containing per-vertex attribute data.

IDLgrPlot::SetVertexAttributeData

This method passes a set of per-vertex attribute data to a vertex shader program, which modifies each individual vertex with a vertex's worth of attribute data at a time.

IDLgrPolygon::GetMultiTextureCoord

This method retrieves the texture coordinates associated with a given Unit.

IDLgrPolygon::GetVertexAttributeData

This method retrieves the data associated with a named attribute variable containing per-vertex attribute data.

IDLgrPolygon::SetMultiTextureCoord

This method associates a Unit with a given set of texture coordinates. This lets you layer textures with different texture coordinates onto a polygon when using a shader program.

IDLgrPolygon::SetVertexAttributeData

This method passes a set of per-vertex attribute data to a vertex shader program, which modifies each individual vertex with a vertex's worth of attribute data at a time.

IDLgrPolyline::GetVertexAttributeData

This method retrieves the data associated with a named attribute variable containing per-vertex attribute data.

IDLgrPolyline::SetVertexAttributeData

This method passes a set of per-vertex attribute data to a vertex shader program, which modifies each individual vertex with a vertex's worth of attribute data at a time.

IDLgrROIGroup::Remove

This method removes an object from the ROI group.

IDLgrSurface::GetMultiTextureCoord

This method retrieves the texture coordinates associated with a given Unit.

IDLgrSurface::GetVertexAttributeData

This method retrieves the data associated with a named attribute variable containing per-vertex attribute data.

IDLgrSurface::SetMultiTextureCoord

This method associates a Unit with a given set of texture coordinates. This lets you layer textures with different texture coordinates onto a surface when using a shader program.

IDLgrSurface::SetVertexAttributeData

This method passes a set of per-vertex attribute data to a vertex shader program, which modifies each individual vertex with a vertex's worth of attribute data at a time.

IDLgrWindow::OnWheel

This method handles notification (from the native window device) that a mouse wheel event has occurred. (Useful only with the IDL Export Bridge.)

IDLitDirectWindow::OnWheel

This method handles notification (from the native window device) that a mouse wheel event has occurred. (Useful only with the IDL Export Bridge.)

IDLitManipulator::OnWheel

This method handles notification (from the native window device) that a mouse wheel event has occurred. (Useful only with the IDL Export Bridge.)

IDLitManipulatorContainer::OnWheel

This method handles notification (from the native window device) that a mouse wheel event has occurred. (Useful only with the IDL Export Bridge.)

IDLitWindow::OnWheel

This method handles notification (from the native window device) that a mouse wheel event has occurred. (Useful only with the IDL Export Bridge.)
