Remarks

This node sets the current shape complexity value. This is a heuristic value which provides a hint at what geometric complexity to render shape nodes. Values range from 0 to 1, where 0 means minimum complexity and 1 means maximum complexity. Each shape node interprets complexity in its own way.

Shape complexity (OIV.Inventor.Nodes.SoComplexity.value field)

Shape complexity always affects rendering and primitive generation for the OIV.Inventor.Actions.SoCallbackAction. For some shapes, it also affects picking.

There are three ways to interpret shape complexity, depending on the OIV.Inventor.Nodes.SoComplexity.type field.

The following is a sampling of the effects of shape complexity.

Texture quality

The OIV.Inventor.Nodes.SoComplexity node also controls the quality of textures applied to shapes, based on the value of the OIV.Inventor.Nodes.SoComplexity.textureQuality field.

For texture nodes (OIV.Inventor.Nodes.SoTexture2, OIV.Inventor.Nodes.SoTextureCubeMap, etc), textureQuality controls the OpenGL minFilter, magFilter and mipmap settings that the hardware will use when applying the texture image to the geometry. With the default value (0.5) textures are not interpolated. We recommend using a higher value, e.g. 0.75, on modern graphics hardware.

For text nodes (OIV.Inventor.Nodes.SoText2, OIV.Inventor.Nodes.SoText3, etc), when the OIV.Inventor.Nodes.SoFont renderStyle field is set to TEXTURE, the OpenGL settings controlled by textureQuality strongly affect the quality of the text rendering. With the default value (0.5) textures are not interpolated, so text may appear to not be anti-aliased. We recommend using a higher value, e.g. 0.75, on modern graphics hardware.

In a few cases, e.g. OIV.Inventor.Nodes.SoImageBackground, setting textureQuality to zero disables rendering complexity.

ACTION BEHAVIOR

OIV.Inventor.Actions.SoGLRenderAction, OIV.Inventor.Actions.SoCallbackAction, OIV.Inventor.Actions.SoGetBoundingBoxAction, OIV.Inventor.Actions.SoRayPickAction Sets the current complexity in the state. Sets: OIV.Inventor.Elements.SoComplexityElement, OIV.Inventor.Elements.SoComplexityTypeElement, OIV.Inventor.Elements.SoTextureQualityElement
