| source | コピー元の画像 |
| dest | コピー先の RenderTexture オブジェクト。 null の場合、直接画面に転送する |
| mat | Material to use for copying. Material's shader should do some post-processing effect. |
| offsets | Variable number of filtering offsets. Offsets are given in pixels. |
Copies source texture into destination, for multi-tap shader.
This is mostly used for implementing some image effects. For example,
Gaussian or iterative Cone blurring samples source texture at multiple different locations.
Requires Unity Pro.
BlitMultiTap sets dest to be active render texture, sets source as
_MainTex property on the material, and draws a full-screen quad. Each vertex of the quad
has multiple texture coordinates set up, offset by offsets pixels.
