Declaration

public static void DrawTexture3DVolume(Texture texture, float opacity = 1.0f, float qualityModifier = 1.0f, FilterMode filterMode = FilterMode.Bilinear, bool useColorRamp = false, Gradient customColorRamp = null);

Parameters

texture The volumetric texture to draw.
opacity The non-linear volume opacity modifier. Use this to control the opacity of the visualization. Valid values are 0-1, inclusive. A value of 1 is fully opaque and a value of 0 is fully transparent. The default value is 1.
qualityModifier Sets the sample per texture pixel count. Higher values result in a higher quality render. The default value is 1.
filterMode Sets the texture filtering mode to use.
useColorRamp Enables color ramp visualization.
customColorRamp The custom gradient that Unity uses as a color ramp. If this is not specified, Unity uses Google Turbo color ramp.

Description

Draws a 3D texture using Volume rendering mode in 3D space.


Teapot volume rendered with a gradient that has a transparent black outline.


Noise volume with fire gradient applied.
