ISharpEngineSceneViewSupersamplingCount Property

float SupersamplingCount { get; set; }

Property Value

SupersamplingCount defines the super-sampling count (SSAA) - how many more pixels are rendered for each final pixel.

When SSAA is more than 1, then the rendering is done on a scaled texture that has SupersamplingCount-times more pixels that the final texture (width and height are scaled by the SupersamplingFactor and set to RenderWidth and RenderHeight) At the end of the rendering this super-scaled texture is down-sampled into the texture with the final size (defined by Width and Height).

Valid values are from 1 (no super-sampling) to 64 and are limited by the max texture size that is supported by the GPU device.

Value 4 means that width and height are multiplied by 2 and this produces a texture with 4 times as many pixels. Value 2 means that width and height are multiplied by 1.41 (sqrt(2) = 1.41) and this produces a texture with 2 times as many pixels.

After initializing the SceneView, the SupersamplingCount gets the actually used super-sampling count.

If this value is not manually set by the user, then during initialization the GetDefaultSuperSamplingCount(PhysicalDeviceDetails) method is called to set the super-sampling count for the used GPU device (by default SSAA is set to 4 for dedicated desktop devices, for integrated desktop devices is 2, for mobile and low-end devices the default value is 1.

Changing this value after the SceneView is initialized will call SceneView.Resize method with the new super-sampling count.

Because super-sampling can significantly influence the rendering performance, it is highly recommended that the user of the application can manually adjust this setting.
