Just FYI, the __vfptr = CXX0030 thing is because the debugger thinks that d3ddev is pointing to an actual instance of a D3D device, if there's some error in the call to CreateDevice, and for whatever...

The function call CreateDevice returns a HRESULT (error code), so do:

HRESULT result = CreateDevice (...);

the possible values are defined as D3D_OK, D3DERR_DEVICELOST, D3DERR_INVALIDCALL,...

Ah ok. There shouldn't be any problem with doing what you're doing from a DLL. I have only ever written DX applications that are staticly linked and DLLs that don't do anything DX, so I don't know...

Oh, and the reason that a D3DPRESENT_PARAMETERS object 'just works' is that the D3DPRESENT_PARAMETERS is a value (structure) type not a pointer type.

Learn this distinction ASAP.

You're just creating a pointer variable without actually setting it to anything, so what you're getting is 'worse' than a null pointer, it's a pointer to some random location. The message in the...

It's because you are using an orthographic projection, in an orthographic projection, a higher depth doesn't make objects appear smaller.

See : http://www.songho.ca/opengl/gl_projectionmatrix.html...

Matrix transforms are perhaps harder to initially understand than applying offsets and rotations directly to points, but it's IMO the 'right choice' to use matrices, because it makes everything in...

What kind of 2D library? Graphics, or physics? or something else?

I like this book alot, it says collision detection, but it also has a lengthly intro to many of the concepts of simulated 'space...

It's easy enough to arbitrarily set the rotation point, e.g. this will work:


case 'E':
case 'e':
{
//Rotation of the red square.

You setup an orthographic projection matrix, and then in the pushmatrix/popmatrix block, you load a matrix in model space, this 'undoes' your projection until the matrix is popped...

You can't really modify the .a file, it contains already compiled code and symbols. You can however modify the source code and rebuild the library with whatever changes you need. Exactly how to do...

looks like you have not called glEnable ( GL_DEPTH_TEST );

otherwise, post code

It seems that GLFW doesn't properly initialize the opengl state machine until you call glfwOpenWindow.

Move the call to glEnable ( GL_DEPTH_TEST ); to somewhere after the call to glfwOpenWindow....

Some things:

- Check the return value of LoadBitmap ( i.e. does the bitmap load atall? ).

- You are loading the file "art" ( without a file extension ). If you want to fopen "art.bmp" file,...

From main, (after calling glutInit and before calling glutMainLoop), call your bitmap load function, put the return value into a global int variable ( e.g. texture1 ), repeat for however many...

The nicest solution (in terms of future flexibility), is to encode your data in either a bitmap image or a text file.

Alternatively, if you just want to initialize an array of arrays:

I'm not suprised that you're finding it hard to get hold of Maya 4.0, it's pretty ancient. What kind of plugin is the one you need? Is it one of those Maya pseudo-dlls or a MEL script? If it's a MEL...

Cool; good to know it's working :)

Disregard my last post; although, the -g3 flag is quite useful to remember ( with full debug info you can see all the values passed into methods aswell as the...

Ok, the method NodeGL:plot is very small, the only thing that could be wrong in that method itself is the array not being instantiated ( or being too short ), however, there could be something wrong...

There is probably something wrong in your not-shown classes ColorGL &| BezierGL, since the code runs fine with all reference to those classes commented.

Have you got a debugger? I'm guessing if...

As long as its always the negative of what it should be; you're ok to put in a * -1, you could also try swapping the cos and sin exprs around, so that movex is the sin, and movey is the cos. I...

there's at least one mistake in the diagram; the line labeled "rho" is actually not rho; you need to calculate the length of that line to work out phi, so rename the line rho on the diagram to the...

I've attached a new image showing how to get rho,phi and theta values on a sphere; bear in mind these equations have only been tested mentally, so look carefully at the proofings. You may find that...

it actually only converts a Y to a Z (2D), the value of Z also has to be in terms of the X to be a sphere; to convert them to a spherical system, rho will equal Z, phi will equal Y, and theta will be...

If you were only using a circle, not a sphere, it's simple trigonometry; sphere is abit more difficult though, do you have to take rotation (of the sphere) into account?

For a circle though; see...
