<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].

<member name="curve" type="Curve" setter="set_curve" getter="get_curve">
|
|
The [Curve] that is rendered onto the texture.

<member name="texture_mode" type="int" setter="set_texture_mode" getter="get_texture_mode" enum="CurveTexture.TextureMode" default="0">
|
|
The format the texture should be generated with. When passing a CurveTexture as an input to a [Shader], this may need to be adjusted.

|
|
<member name="width" type="int" setter="set_width" getter="get_width" default="256">
|
|
The width of the texture (in pixels). Higher values make it possible to represent high-frequency data better (such as sudden direction changes), at the cost of increased generation time and memory usage.

<constants>

<constant name="TEXTURE_MODE_RGB" value="0" enum="TextureMode">
|
|
Store the curve equally across the red, green and blue channels. This uses more video memory, but is more compatible with shaders that only read the green and blue values.
|
|
</constant>
|
|
<constant name="TEXTURE_MODE_RED" value="1" enum="TextureMode">
|
|
Store the curve only in the red channel. This saves video memory, but some custom shaders may not be able to work with this.
