Public Member Functions

void

draw (GLint first=0, GLsizei count=-1)

Draws the Batch . Optionally specify a first vertex/element and a count . Otherwise the entire geometry will be drawn.
void

bind ()
GLenum

getPrimitive () const

Returns OpenGL primitive type (GL_TRIANGLES, GL_TRIANGLE_STRIP, etc)
size_t

getNumVertices () const

Returns the total number of vertices in the associated geometry.
size_t

getNumIndices () const

Returns the number of element indices in the associated geometry; 0 for non-indexed geometry.
GLenum

getIndexDataType () const

Returns the data type for indices; GL_UNSIGNED_INT or GL_UNSIGNED_SHORT.
const GlslProgRef &

getGlslProg () const

Returns the shader associated with the Batch .
void

replaceGlslProg (const GlslProgRef &glsl)

Replaces the shader associated with the Batch . Issues a warning if not all attributes were able to match.
const VaoRef

getVao () const

Returns the VAO mapping the Batch 's geometry to its shader.
VboMeshRef

getVboMesh () const

Returns the VboMesh associated with the Batch .
void

replaceVboMesh (const VboMeshRef &vboMesh)

Replaces the VboMesh associated with the Batch . Issues a warning if not all attributes were able to match.
void

reassignContext (Context *context)

Changes the GL context the Batch is associated with.

BatchRef

create (const VboMeshRef &vboMesh, const gl::GlslProgRef &glsl, const AttributeMapping &attributeMapping=AttributeMapping())

Builds a Batch from a VboMesh and a GlslProg . Attributes defined in attributeMapping override the default mapping between AttributeSemantics and GlslProg attribute names.
BatchRef

create (const geom::Source &source, const gl::GlslProgRef &glsl, const AttributeMapping &attributeMapping=AttributeMapping())

Builds a Batch from a geom::Source and a GlslProg . Attributes defined in attributeMapping override the default mapping.

Batch (const VboMeshRef &vboMesh, const gl::GlslProgRef &glsl, const AttributeMapping &attributeMapping)
Batch (const geom::Source &source, const gl::GlslProgRef &glsl, const AttributeMapping &attributeMapping)
void

init (const geom::Source &source, const gl::GlslProgRef &glsl)
void

initVao (const AttributeMapping &attributeMapping=AttributeMapping())
