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);Forgive your enemies - it messes with their heads

You could convert your product to OpenGL. :-D

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!

Mathematically, yes...in reality, it remains to be proved.

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.

String Theory[^] And even Uncertainty is uncertain[^]. It depends on more dimensions than can be explained at the moment.

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.

You're joking, right? V = s4.

V = s4? Are you sure? Rotating Hypercube[^], not easy is it? Some information[^]. Want to try again?

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.

He is intelligent, but not experienced. His pattern indicates two-dimensional thinking.

A serious question: Isn't moving pixel sized triangles quicker with modern GPUs anyway? I assumed it was, still a PITA though.

So you need a point with the circular aspect excluded. i.e. :beer:

You mean its hyper-surface area.

I don't even know what that means. http://www.wolframalpha.com/input/?i=tesseract+volume[^]

As a dimension, yes, it is a theory.

A Dead ringer for Kate Winslett[^]Maybe, I still have to look into how to draw a pixel sized triangle that remains pixel sized regardless of how much the user zooms in/out. In OpenGL/DirectX 9 this used to be quite easy, but now you have to get into vertex shaders, texture mapping and such just to draw a dot. So instead of just doing a few lines of code and be done with it, now you have to research for a day how to draw a dot.
