4.1.3.9. PrimitiveVertexArray¶

This modules provides tools to draw segments and rectangles primitives.

The aim of these classes has to be used by a Geometry Shader.

class PyOpenGLng.HighLevelApi.PrimitiveVertexArray.GlLinesVertexArray(objects=None)[source]¶

Bases: PyOpenGLng.HighLevelApi.VertexArrayObject.GlVertexArrayObject

Base class to draw primitives as lines.

bind_to_shader(shader_program_interface_attribute)[source]¶

Bind the vertex array to the shader program interface attribute.

draw()[source]¶

Draw the vertex array as lines.

set(objects)[source]¶

class PyOpenGLng.HighLevelApi.PrimitiveVertexArray.GlRectangleVertexArray(rectangles=None)[source]¶

Bases: PyOpenGLng.HighLevelApi.PrimitiveVertexArray.GlLinesVertexArray

Base class to draw rectangles primitives as lines.

set(rectangles)[source]¶

Set the vertex array from an iterable of rectangles.

class PyOpenGLng.HighLevelApi.PrimitiveVertexArray.GlSegmentVertexArray(segments=None)[source]¶

Bases: PyOpenGLng.HighLevelApi.PrimitiveVertexArray.GlLinesVertexArray

Base class to draw segments primitives as lines.

_logger = <logging.Logger object at 0x56fdc10>¶

set(segments)[source]¶

Set the vertex array from an iterable of segments.

class PyOpenGLng.HighLevelApi.PrimitiveVertexArray.TriangleVertexArray(items=None)¶

Bases: PyOpenGLng.HighLevelApi.VertexArrayObject.GlVertexArrayObject

Base class to draw primitives as triangles.

bind_to_shader(shader_program_interface)¶

Bind the vertex array to the shader program interface attribute.

draw()¶

Draw the vertex array as lines.

set(positions, normals, colours)¶

Set the vertex array from an iterable of triangles.
