SoView2DExtensionSampler¶

InventorModule¶

genre	`View2DExtended`
author	`MeVis Medical Solutions AG`
package	`MeVisLab/Standard`
dll	`SoView2D`
definition	SoView2DShader.def
inherits from	`SoView2DExtension`
keywords	`GLSL`

Purpose¶

The SoView2DExtensionSampler module allows for rendering SoView2D extensions to an RGBA texture. This texture can be given a name and can be rendered/accessed by a SoView2DShaderOverlay. A typical use case would be to render a SoView2DScene to a texture using this module and to write a custom SoView2DShaderFunction which modifies the rendering depending on the content of the texture.

Visible Fields¶

Drawing On¶

name: drawingOn, type: Bool, default: TRUE¶: Enables/Disables rendering of the scene below the module to the texture.

Render On Slab¶

name: renderOnSlab, type: Bool, default: TRUE¶: If checked, the rendering on slab is enabled.

Overlay Name¶

name: overlayName, type: String, default: texture¶: Sets the overlay name for usage in SoView2DShaderOverlay.

Filter Mode¶

name: filterMode, type: Enum, default: FILTER_LINEAR_POSTCLASS¶: Defines the filter mode that is used when rendering the result texture (e.g. in the SoView2DShaderOverlay)

Values:

Title	Name
Nearest	FILTER_NEAREST
Linear Postclass	FILTER_LINEAR_POSTCLASS

Blend Mode¶

name: blendMode, type: Enum, default: BLEND_PREMULTIPLIED_BLEND¶: Defines the blend mode that is used when rendering the result texture (e.g. in the SoView2DShaderOverlay)

Values:

Title	Name
Replace	BLEND_REPLACE
Add	BLEND_ADD
Screen	BLEND_SCREEN
Blend	BLEND_BLEND
Premultiplied Blend	BLEND_PREMULTIPLIED_BLEND
Maximum	BLEND_MAXIMUM
Minimum	BLEND_MINIMUM
Reverse Subtract	BLEND_REVERSE_SUBTRACT
Subtract	BLEND_SUBTRACT

Enable Multi Sampling¶

name: enableMultiSampling, type: Bool, default: FALSE¶: Enabled multisampling (MSAA) using Multi Sampling number of samples. This can improve the rendering quality/anti-aliasing when using a SoView2DScene and normal Inventor rendering below this module.
