    Uhm, no. In math, a point has exactly zero dimensions. It's infinitely small and not much to draw therefore. What you probably want to do is to set a small (but not not infinitely small) sprite or billboard at some 3D coordinates.

    There is a point in time when it is not there. There is a point in time when it is. Then there is a another point in time when it ceases. If you wish to talk maths then please continue, but be aware that there are a lot more than three dimensions, and that the temporal and hyperspatial ones can do some odd things. Have you ever worked out the volume of a tesseract (aka a Hypercube)? Very difficult, and what about projections of future positions of known points, a clock is useful there!

      But in 3D, a point consists of 3 dimensions - x/y and z.

      My, what a small minded race the humans are. Only three dimensions? Pfft...Do you not own a clock?

          We have made those classes ourselves, this is not problematic. The problematic part is that there's no PointList primitive, just LineList, LineStrip, TriangleList, TriangleStrip.

          Is it possible to make a line with length of one instead. I don't think anyone can tell the difference.

            You could, but very inconvenient, because the length 1 is in screen space, whilst you normally define all vertices in model space, and then position your camera etc etc. So to do the dots you'd have to mess up the whole standard rendering pipeline.

                You can, but you need to download the XNA Math Helper[^] first. Then you can use the VertexPositionColor and Vector3 classes to help you. For instance:

                Vector3 pt = new Vector3(1,1,0);
                VertexPositionColor[] vertices = new VertexPositionColor[1];
                vertices[0] = new VectorPositionColor(pt, color); // Where color is the colour of the brush
                VertexBuffer vertexBuffer = new VertexBuffer(device, VertexPositionColor.VertexDeclaration, vertices.Length, BufferUsage.WriteOnly);
                vertexBuffer.SetData(0, vertices, 0, vertices.Length, 0);
                device.SetVertexBuffer(vertexBuffer);

                      Our product already does OpenGL. I mentioned on the MSDN forum that OpenGL 1.1 can do points, but this invoked a "I know, OpenGL..., but let's be realistic" reply...

                        Indeed I do, but you may note that I clearly stated "in 3D". By default, Silverlight 3D exists in 4D.

                                I know of String Theory, and how it has failed to produce a single concrete prediction. Give any mathematical model enough degrees of freedom and you can make it look like anything. I'm not convinced it is the answer.

                                      OK. A tesseract is a cube extruded along the w-axis a distance of s. Hence, V = s4.

                                        OK. A tesseract is a cube extruded along the w-axis a distance of s. Hence, V = s4.

                                        You are falling into the trap that I fell into. That is it's volume in n Dimensional space. To work out it's volume in n-1 dimensional space is where it gets interesting. The volume then rather different, it is larger on the inside than the outside. Exterior volume is only the same as in n-1 space, whereas the internal volume is the n analogue. However the internal volume cannot be accessed from an n dimensional viewpoint.

                                          Indeed I do, but you may note that I clearly stated "in 3D". By default, Silverlight 3D exists in 4D.
