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
Draws a 3D texture using Slice rendering mode in 3D space.
Head scan rendered in slice mode with a custom gradient.
