[gluon] Gluon Graphics

[idk <istdasklar@xxxxxxxxx>]

Hello,

I want to show you what I m doing in Gluon Graphics and I m waiting for your suggest

GluonGraphics::Vertex represents a 3d point

It contains x,y,z, QColor, textureX, textureY .

GluonGraphics::Transform represents a transformation Matrix

it contains a QMatrix4x4 and contains many methods like : setRotate, setPosition ....

GluonGraphics::Mesh represents an object to show.

It contains a VertexList, and many methods to create primitiv shape. For example : createBox, createCircle , createPlane ....

GluonGraphics::Item : has a mesh and a Transform class. This class can paint the mesh and apply transformation to openGL.

Now the question : How Can I split 2d function and 3d function...

First solution : 

Keep one class for 2d and 3d.

Example : 

Transform::setPosition( float x, float y, float z=0);

item->setPosition(x,y);

item->setPosition(x,y,z);

Mesh::createRect( QRectF )

Mesh::createCone(radius, width....)

2nd solution : 

2d and 3d class inherits from one

Example : 

Transform2d::setPosition(float x, float y);

Transform3d::setPosition(float x, float y, float z);

Mesh2d::createRect()

Mesh3d::createCone()

3th Solution :

1 global class for transformation and 2 for mesh :

Transform::setPosition(float x,float y, float z=0);

Mesh2d::createRect(QRect);

Mesh3d::createBox(....)

I this the solution 3 is the best. So I m waiting now for your suggest
