Member Function Documentation

GetDebug()

void GPU_Deposition::GetDebug

(

ScalarField2 &

sf

)

Gets the debug data back to the CPU. The content of the debug buffer can be modified in the shader.

Parameters

sf	ScalarField to store the debug data.

GetHeight()

void GPU_Deposition::GetHeight

(

ScalarField2 &

sf

)

Gets the elevation data back to the CPU.

Parameters

sf	ScalarField to store the elevation data.

GetSed()

void GPU_Deposition::GetSed

(

ScalarField2 &

sf

)

Gets the added sediment data back to the CPU.

Parameters

sf	ScalarField to store the added sediment data.

GetStream()

void GPU_Deposition::GetStream

(

ScalarField2 &

sf

)

Gets the sediment stream data back to the CPU.

Parameters

sf	ScalarField to store the stream data.

Init()

void GPU_Deposition::Init

(

const HeightField &

hf

)

GPU buffers initialization from given heightfield. Shader and Uniforms are also initialized.

Parameters

hf	Heightfield to be used as bedrock.

SetSourceMap()

void GPU_Deposition::SetSourceMap

(

const ScalarField2 &

source_map

)

Sets a source map for the sediments. Sediments will be produced by the source map, and transported everywhere according to the simulation.

Parameters

source_map

ScalarField to be used as source map.

SetUniforms()

void GPU_Deposition::SetUniforms

(

float

deposition_strength

)

Set the uniform variable associated to deposition strength.

Parameters

deposition_strength

Deposition strength value.

Step()

void GPU_Deposition::Step

(

int

nb_steps

)

Launches nb_steps steps of the deposition simulation.

Parameters

nb_steps

Number of simulation steps to launch.
