Detailed Description

Render atoms as sphere meshes.

Remarks

See also

HierarchicalTriangularMesh.

Remarks

The level of detail can be automatically de-scaled with distance.

The level of detail can be overriden.

Constructor & Destructor Documentation

AtomRenderer()

AtomRenderer::AtomRenderer ( const std::vector< Atom > &  atoms, uint8_t  levelOfDetail = 0, glm::vec3  cameraPosition = glm::vec3(0), BASE_MESH  mesh = BASE_MESH::ANY, float  clipCorrection = 1.5f  )

inline

Construct a new AtomRenderer from a BASE_MESH type.

Remarks

BASE_MESH::ANY will sample from refinements of all BASE_MESH types. Giving a finer range of level of detail .

Choosing a specific BASE_MESH will mean the level of detail is refinements of just that mesh.

Parameters

atoms	the atoms to draw.
levelOfDetail	the level of detail.
cameraPosition	the cartesian position of the camera.
mesh	the base mesh type.

See also

BASE_MESH.

Parameters

clipCorrection

correction factor for impostor rendering.

Member Function Documentation

draw()

void AtomRenderer::draw ( bool  imposters = true )

inline
