CurveTexture

繼承： Texture2D < Texture < Resource < RefCounted < Object

一維紋理，其中像素亮度對應於曲線上的點。

說明

A 1D texture where pixel brightness corresponds to points on a unit Curve resource, either in grayscale or in red. This visual representation simplifies the task of saving curves as image files.

If you need to store up to 3 curves within a single texture, use CurveXYZTexture instead. See also GradientTexture1D and GradientTexture2D.

屬性

Curve	curve
bool	resource_local_to_scene	false (overrides Resource)
TextureMode	texture_mode	0
int	width	256

列舉

enum TextureMode: 🔗

TextureMode TEXTURE_MODE_RGB = 0

將曲線平均儲存在紅色、綠色和藍色通道上。這會使用更多的顯存，但與唯讀取綠色和藍色值的著色器更相容。

TextureMode TEXTURE_MODE_RED = 1

僅將曲線儲存在紅色通道中。這可以節省顯存，但某些自訂著色器可能無法使用它。

屬性說明

Curve curve 🔗

• void set_curve(value: Curve)

• Curve get_curve()

The Curve that is rendered onto the texture. Should be a unit Curve.

---

TextureMode texture_mode = 0 🔗

• void set_texture_mode(value: TextureMode)

• TextureMode get_texture_mode()

生成紋理時應使用的格式。當將 CurveTexture 作為輸入傳遞給 Shader 時，可能需要調整。

---

int width = 256 🔗

• void set_width(value: int)

• int get_width()

紋理寬度（單位為圖元）。較大的值能夠更好地表示高頻資料（例如方向的突變），但會增加生成時間和記憶體佔用。
