Detailed Description

Used to convert old immediate mode OpenGL code to OpenGL 3+ core.

Named as such to discourage use by end-users of G3D.

Old immediate mode: rd->setTexture(0, t); glBegin(PrimitiveType::TRIANGLES); { glColor(...); glMultiTexCoord(0, ...); glVertex(...); glMultiTexCoord(0, ...); glVertex(...); glMultiTexCoord(0, ...); glVertex(...); } glEnd();

New Code: SlowMesh m(PrimitiveType::TRIANGLES); { m.setTexture(t); m.setColor(...); m.setTexCoord(...); m.makeVertex(...); m.setTexCoord(...); m.makeVertex(...); m.setTexCoord(...); m.makeVertex(...); } m.render(rd);

Alternatively, if you already have a CPUVertexArray:

SlowMesh m(PrimitiveType::TRIANGLES, cpuVertexArray, texture); m.render(rd);

Member Function Documentation

◆ makeVertex() [1/3]

void G3D::SlowMesh::makeVertex ( const Vector2 & vertex )

Construct a Vertex given the current texCoord, color, and normal state.

◆ makeVertex() [2/3]

void G3D::SlowMesh::makeVertex ( const Vector3 & vertex )

◆ makeVertex() [3/3]

void G3D::SlowMesh::makeVertex ( const Vector4 & vertex )

◆ render()

void G3D::SlowMesh::render	(	RenderDevice *	rd,
		int	coverageSamples = `1`
	)		const

Constructs a VertexBuffer from the vertex array, and renders it using a simple shader that mimics the old fixed-function pipeline.

Parameters

coverageAntialiasingMode If greater than 1, use multisampling for coverage. This only works with depth and stencil disabled.

◆ reserveSpace()

void G3D::SlowMesh::reserveSpace ( int numVertices )

Call to reserve space in the CPU array for.

Parameters

numVertices Vertices, to avoid continous reallocation. This is to make use of SlowMesh slightly faster for large vertex counts, but custom code bypassing SlowMesh should be used for optimal performance.

◆ setColor() [1/2]

void G3D::SlowMesh::setColor ( const Color3 & color )

Change the currently set color state, defaulted to black.

◆ setColor() [2/2]

void G3D::SlowMesh::setColor ( const Color4 & color )

◆ setNormal()

void G3D::SlowMesh::setNormal ( const Vector3 & normal )

Change the currently set color state, defaulted to (0,0,1)

◆ setPointSize()

void G3D::SlowMesh::setPointSize ( const float size )

◆ setPrimitveType()

void G3D::SlowMesh::setPrimitveType ( const PrimitiveType & p )

Overrides the current PrimitiveType, all of the create vertices will be of said type, whether made before or after this call.

◆ setTexCoord()

void G3D::SlowMesh::setTexCoord ( const Vector2 & texCoord )

Change the currently set texCoord state, defaulted to (0,0)

◆ setTexture()

void G3D::SlowMesh::setTexture ( const shared_ptr< Texture > t )

Sets the texture to use for rendering.
