GetHeightfieldAabb()

virtual AZ::Aabb Physics::HeightfieldProviderRequests::GetHeightfieldAabb ( ) const

pure virtual

Returns the AABB of the heightfield. This is provided separately from the shape AABB because the heightfield might choose to modify the AABB bounds.

Returns

AABB of the heightfield.

GetHeightfieldGridColumns()

virtual AZ::u64 Physics::HeightfieldProviderRequests::GetHeightfieldGridColumns ( ) const

pure virtual

Returns the height field gridsize columns.

Returns

the size of the grid in the x direction.

GetHeightfieldGridRows()

virtual AZ::u64 Physics::HeightfieldProviderRequests::GetHeightfieldGridRows ( ) const

pure virtual

Returns the height field gridsize rows.

Returns

the size of the grid in the y direction.

GetHeightfieldGridSize()

virtual void Physics::HeightfieldProviderRequests::GetHeightfieldGridSize ( size_t &  numColumns, size_t &  numRows  ) const

pure virtual

Returns the height field gridsize.

Parameters

numColumns	contains the size of the grid in the x direction.
numRows	contains the size of the grid in the y direction.

GetHeightfieldGridSpacing()

virtual AZ::Vector2 Physics::HeightfieldProviderRequests::GetHeightfieldGridSpacing ( ) const

pure virtual

Returns the distance between each height in the map.

Returns

Vector containing Column Spacing, Rows Spacing.

GetHeightfieldHeightBounds()

virtual void Physics::HeightfieldProviderRequests::GetHeightfieldHeightBounds ( float &  minHeightBounds, float &  maxHeightBounds  ) const

pure virtual

Returns the height field min and max height bounds.

Parameters

minHeightBounds	contains the minimum height that the heightfield can contain.
maxHeightBounds	contains the maximum height that the heightfield can contain.

GetHeightfieldIndicesFromRegion()

virtual void Physics::HeightfieldProviderRequests::GetHeightfieldIndicesFromRegion ( const AZ::Aabb &  region, size_t &  startColumn, size_t &  startRow, size_t &  numColumns, size_t &  numRows  ) const

pure virtual

Return the specific heightfield row/column data that exists inside a given AABB region.

Parameters

region	The input region to get row/column data for
startColumn	[out] The starting heightfield column index for that region
startRow	[out] The starting heightfield row index for that region
numColumns	[out] The number of columns that exist within the region
numRows	[out] The number of rows that exist within the region

GetHeightfieldMaxHeight()

virtual float Physics::HeightfieldProviderRequests::GetHeightfieldMaxHeight ( ) const

pure virtual

Returns the height field max height bounds.

Returns

the maximum height that the heightfield can contain.

GetHeightfieldMinHeight()

virtual float Physics::HeightfieldProviderRequests::GetHeightfieldMinHeight ( ) const

pure virtual

Returns the height field min height bounds.

Returns

the minimum height that the heightfield can contain.

GetHeightfieldTransform()

virtual AZ::Transform Physics::HeightfieldProviderRequests::GetHeightfieldTransform ( ) const

pure virtual

Returns the world transform for the heightfield. This is provided separately from the entity transform because the heightfield might want to clear out the rotation or scale.

Returns

world transform that should be used with the heightfield data.

GetHeights()

virtual AZStd::vector<float> Physics::HeightfieldProviderRequests::GetHeights ( ) const

pure virtual

Returns the list of heights used by the height field.

Returns

the rows*columns vector of the heights.

GetHeightsAndMaterials()

virtual AZStd::vector<Physics::HeightMaterialPoint> Physics::HeightfieldProviderRequests::GetHeightsAndMaterials ( ) const

pure virtual

Returns the list of heights and materials used by the height field.

Returns

the rows*columns vector of the heights and materials.

GetMaterialList()

virtual AZStd::vector<AZ::Data::Asset<Physics::MaterialAsset> > Physics::HeightfieldProviderRequests::GetMaterialList ( ) const

pure virtual

Returns the list of materials used by the height field.

Returns

returns a vector of all materials.
