VertBatch (GLenum primType=GL_POINTS, bool useContextDefaultBuffers=true)

Constructs a VertBatch with primitive type primType . Default is GL_POINTS . If useContextDefaultBuffers is true , uses default buffers for the context, saving allocations; suitable for single draw.
void

setType (GLenum type)

Sets the primitive type of the VertBatch . Default is GL_POINTS .
GLenum

getType () const

Returns the primitive type of the VertBatch . Default is GL_POINTS .
void

void

vertex (const vec4 &v, const ColorAf &c)

Locks the values for the current vertex and sets its position (attribute geom::POSITION ) and color ( geom::COLOR ). Call after any corresponding calls to color() , normal() and/or texCoord() . Should not be called if you have called color() prior.
void

begin (GLenum type)

Resets the sequence of vertices and sets the VertBatch 's primitive type.
void

end ()

No-op. Present for parity with legacy immediate mode.
void

clear ()

Clears all vertices recorded by the VertBatch .
bool

empty () const

Returns true if no vertices have been added to the VertBatch .
void

draw ()

Draws the VertBatch using the gl::Context 's currently active shader. For multiple draws consider constructing a gl::Batch using the VertBatch instead.

VertBatchRef

create (GLenum primType=GL_POINTS, bool useContextDefaultBuffers=false)

Creates a VertBatchRef with primitive type primType . Default is GL_POINTS . If useContextDefaultBuffers is false , allocates and uses internal buffers and VAO; suitable for multiple draws.
