Method Detail

newMesh

public static R2ProjectionMeshType newMesh(com.io7m.jcanephora.core.api.JCGLInterfaceGL33Type g,
                                           R2ProjectionType p,
                                           com.io7m.jcanephora.core.JCGLUsageHint array_hint,
                                           com.io7m.jcanephora.core.JCGLUsageHint index_hint)

Construct a mesh based on the given projection.

Parameters:

g - A GL interface

p - The initial projection

array_hint - The usage hint for the array buffer that backs the mesh

index_hint - The usage hint for the index buffer that backs the mesh indices

Returns:

A new mesh

arrayObject

public com.io7m.jcanephora.core.JCGLArrayObjectUsableType arrayObject()

Specified by:

arrayObject in interface R2ProjectionMeshReadableType

Returns:

The array object for the mesh

projectionReadable

public R2ProjectionReadableType projectionReadable()

Specified by:

projectionReadable in interface R2ProjectionMeshReadableType

Returns:

A readable reference to the mesh's projection

isUpdateRequired

public boolean isUpdateRequired()

Specified by:

isUpdateRequired in interface R2ProjectionMeshReadableType

Returns:

true iff the values of the projection have changed more recently than the last call to R2ProjectionMeshWritableType.updateProjection(com.io7m.jcanephora.core.api.JCGLArrayBuffersType)

delete

public void delete(com.io7m.jcanephora.core.api.JCGLInterfaceGL33Type g)
            throws R2Exception

Description copied from interface: R2DeletableType

Delete the current object.

Specified by:

delete in interface R2DeletableType

Parameters:

g - An OpenGL interface

R2Exception - On errors

isDeleted

public boolean isDeleted()

Specified by:

isDeleted in interface com.io7m.jcanephora.core.JCGLResourceUsableType

updateProjection

public void updateProjection(com.io7m.jcanephora.core.api.JCGLArrayBuffersType ga)

Description copied from interface: R2ProjectionMeshWritableType

Update the mesh for the current projection.

Specified by:

updateProjection in interface R2ProjectionMeshWritableType

Parameters:

ga - An array buffer interface

projectionWritable

public R2ProjectionType projectionWritable()

Specified by:

projectionWritable in interface R2ProjectionMeshWritableType

Returns:

A writable reference to the mesh's projection
