module Deprecated: UV Parametisation and Grouping
This module is deprecated and will be removed.
About the libraries
The GeoAtlas library contains:
A UV Parametiser for reshaping UVs to minimised surface area distortion.
Two triangle grouping systems, an edge-based method for discovering charts to parametise, and a vertex-based method used by the Enlighten precompute.
For more information on the parametiser and edge-based charting, see the GeoFlattenAndPack() function and the AtlasMesh class.
For more information on the chart identification used by the precompute, see the classes TriGroupSelection and IdentVertLinkBuilder, both in the TriGroup.h file.
Classes
| Name | Description |
|---|---|
| Geo::AtlasMesh | The AtlasMesh implementation used for the packer and anything else that needs not to know whether we have one mesh or several. |
| Geo::AtlasMeshChart | A chart consists of a connected region of the mesh, which has a mapping into a single connected region in UV space. |
| Geo::AtlasMeshChartingFlags | Describe how you would like charting to be performed. |
| Geo::AtlasMeshPackingFlags | This tells the packer how to parameterise your stuff. |
| Geo::AtlasMeshTriangle | An AtlasMesh consists of a number of triangle faces, each composed of three vertices. |
| Geo::AtlasMeshTriangleCorner | A specific corner of a triangle in the mesh can be identified though an AtlasMeshTriangleCorner. |
| Geo::AtlasMeshVertex | An AtlasMesh has a simple vertex format, carrying a single 3D coordinate describing the model, and a single 2D "UV" coordinate though which to provide a unique unwrapping of the mesh into a UV atlas that can be used as high quality light map. |
| Geo::AtlasMeshVertexSplitResult | A specification describing that a specified vertex needs to duplicated, and that some of the m_Corner of the mesh faces need to be relinked to the copy. |
| Geo::ChartParametiserFailure | Details about a chart that failed to parametise well. |
| Geo::GeoFlattenAndPackResults | This class contains all the information about the results of a GeoFlattenAndPack call. |
Enums
| Name | Description |
|---|---|
| eChartParametiserResult | An enum for the types of parametisation results we can get. |
Typedefs
| Name | Description |
|---|---|
| GeoArray< AtlasMeshTriangle > AtlasMeshTriangles | Arrays of triangles. |
| GeoArray< AtlasMeshVertex > AtlasMeshVertices | Arrays of vertices. |
Functions
| Name | Description |
|---|---|
| HasValidFloatData(const AtlasMeshVertices *) | Array version of the per-vertex function of the same name. |
eChartParametiserResult
public: enum eChartParametiserResult
{
PARAM_RESULT_OK = 0,
PARAM_RESULT_OK_BUT_POOR_QUALITY,
PARAM_RESULT_FAILED
}
An enum for the types of parametisation results we can get.
enumerators
| PARAM_RESULT_OK | We produced results. |
| PARAM_RESULT_OK_BUT_POOR_QUALITY | Produced results, but the parametiser had trouble so they may not be ideal. |
| PARAM_RESULT_FAILED | Failed to produce any results. |
bool GEO_CALL Geo::HasValidFloatData
public: bool GEO_CALL HasValidFloatData
(
const AtlasMeshVertices * vs
)
Array version of the per-vertex function of the same name.
