CurveTexture

Inherits: Texture2D < Texture < Resource < RefCounted < Object

A 1D texture where pixel brightness corresponds to points on a curve.

Description

A 1D texture where pixel brightness corresponds to points on a 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.

Enumerations

enum TextureMode:

TextureMode TEXTURE_MODE_RGB = 0

将曲线平均存储在红色、绿色和蓝色通道上。这会使用更多的显存，但与只读取绿色和蓝色值的着色器更兼容。

TextureMode TEXTURE_MODE_RED = 1

仅将曲线存储在红色通道中。这可以节省显存，但某些自定义着色器可能无法使用它。

Property Descriptions

Curve curve

  • void set_curve ( Curve value )

  • Curve get_curve ( )

渲染到纹理上的 Curve。

TextureMode texture_mode = 0

生成纹理时应使用的格式。当将 CurveTexture 作为输入传递给 Shader 时，可能需要调整。

int width = 256

  • void set_width ( int value )

  • int get_width ( )

纹理宽度（单位为像素）。较大的值能够更好地表示高频数据（例如方向的突变），但会增加生成时间和内存占用。
