Declaration
public static void DrawTexture3DSlice(Texture texture, Vector3 slicePositions, FilterMode filterMode = FilterMode.Bilinear, bool useColorRamp = false, Gradient customColorRamp = null);Parameters
| texture | The volumetric texture to draw. |
| slicePositions | The positions of the texture sampling planes. |
| 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
