TextureInterpolation
This component belongs to the category of Engines. This engine creates texture coordinate in 1D according to an input state vector. Coordinate can be interpolated either from min and max value of input states (default behavior) or on a manual define scale.
Create texture coordinate for a given field.
Templates:
- Vec1d
- Vec2d
- Vec3d
Target: Sofa.GL.Component.Engine
namespace: sofa::gl::component::engine
parents:
- DataEngine
Data
| Name | Description | Default value |
|---|---|---|
| name | object name | unnamed |
| printLog | if true, emits extra messages at runtime. | 0 |
| tags | list of the subsets the object belongs to | |
| bbox | this object bounding box | |
| componentState | The state of the component among (Dirty, Valid, Undefined, Loading, Invalid). | Undefined |
| listening | if true, handle the events, otherwise ignore the events | 0 |
| input_coordinates | input array of coordinates values. | |
| scalarField | To interpolate only the first dimension of input field (useful if this component need to be templated in higher dimension). | 1 |
| min_value | minimum value of state value for interpolation. | 0 |
| max_value | maximum value of state value for interpolation. | 0 |
| manual_scale | compute texture interpolation on manually scale defined above. | 0 |
| vertexPloted | Vertex index of values display in graph for each iteration. | 0 |
| graph | Vertex state value per iteration | |
| Inputs | ||
| input_states | input array of state values. | |
| Outputs | ||
| output_coordinates | output array of texture coordinates. | |
| Visualization | ||
| drawPotentiels | Debug: view state values. | 0 |
| showIndicesScale | Debug : scale of state values displayed. | 0.0001 |
