virtual StructuredCoordinateTransformer * inviwo::StructuredCoordinateTransformer::clone ( ) const

overridepure virtual

Implements inviwo::SpatialCoordinateTransformer.

getDataToIndexMatrix()

virtual glm::mat4 inviwo::StructuredCoordinateTransformer::getDataToIndexMatrix ( ) const

pure virtual

Returns the matrix transformation mapping from raw data numbers to voxel index coordinates, i.e. from generally (-inf, inf), ([0,1] for textures) to [0, number of voxels)

Implemented in inviwo::StructuredCoordinateTransformerImpl< N >.

getIndexToDataMatrix()

virtual glm::mat4 inviwo::StructuredCoordinateTransformer::getIndexToDataMatrix ( ) const

pure virtual

Returns the matrix transformation mapping from voxel index coordinates to raw data numbers, i.e. from [0, number of voxels) to generally (-inf, inf), ([0,1] for textures)

Implemented in inviwo::StructuredCoordinateTransformerImpl< N >.

getIndexToModelMatrix()

virtual glm::mat4 inviwo::StructuredCoordinateTransformer::getIndexToModelMatrix ( ) const

pure virtual

Returns the matrix transformation mapping from voxel index coordinates to model space coordinates, i.e. from [0, number of voxels) to (data min, data max)

Implemented in inviwo::StructuredCoordinateTransformerImpl< N >.

getIndexToTextureMatrix()

virtual glm::mat4 inviwo::StructuredCoordinateTransformer::getIndexToTextureMatrix ( ) const

pure virtual

getInverseMetricTensor()

glm::mat3 inviwo::StructuredCoordinateTransformer::getInverseMetricTensor

(

)

const

Computes the inverse metric tensor to be used for gradient computation. Also works for layers with non-orthogonal basis.

The gradient ∇f in world space is then computed based on the partial derivatives in u and v direction ∇f = g_11 ∂f/∂u a_1 + g_12 ∂f/∂u a_2 + g_21 ∂f/∂v a_1 + g_22 ∂f/∂v a_2, where g_ij refers to the inverse metric tensor and a_i to the ith basis vector.

Returns

inverse metric tensor
