• Rodrigo Vieira Maximum Range for Mesh.Intersect Function?

  I am testing for intersections from a point into a mesh at a specified direction, but it only returns hits usually if they are less than 100. I have gotten a 101 before, but, never greater than that. Is there some sort of maximum range for the intersect function I wouldn't imagine there being one, but, if so, how does one extend it Here is my code, in case someone spots an error elsewhere: Function HitMesh( ByRef AnotherMesh As CZoo ...Show All

• CamelbackCinema Moving around in my 3d map..?

  Hi there! I have created a test 3d-map (X-format) and this maps materials and textures is loaded onto a sceneMesh. Then I move around adding/subtracting values to three floats: x , y and x in the following code: device.Transform.View = Matrix.LookAtLH( new Vector3(0,0, z+10.0f), new Vector3(x,y,z), new Vector3(0,1,0));   When you press Left 1 is added to x and Right subtracts 1 from x . Up subtracts 2 from z and Down adds 2 to z ...Show All

• SDK1985 Point Sprite are displayed at the correct place

  Hi, I'm using point sprites in a 2D engine, based on some tutorials. It works quite well, but point sprites are not centered on (X, Y), instead of that, (X, Y) is the lower-right corner. The code is something like: result = lpDirect3DDevice9->SetFVF( D3DFVF_PARTICLEVERTEX ); result = lpDirect3DDevice9->SetRenderState(D3DRS_POINTSPRITEENABLE, TRUE ); result = lpDirect3DDevice9->SetRenderState(D3DRS_POINTSCALEENABLE, FALSE ); result = ...Show All

• Lovericky Only square textures?

  I just found out that, when converting from a bitmap to a texture, directX appears to stretch the bitmap into a square. This is a problem, because if I don't want my external images getting stretched out of shape when they're rendered to the screen, I have to add "empty space" to the bitmap files so that the bitmap is a square. But I've been determining the size of an object on the screen based on the original bitmap that was loa ...Show All

• Technologist Reading a Vertexbuffer from a Mesh

  This has been driving me nuts.  It's so simple... but not working.  I have written to vertex buffers before, no problem.  But, for some reason, I can't read an existing one from a mesh. Keep in mind, I have recently upgraded to the newest version of Managed DirectX. Perhaps something has changed   I would like to dump vertex buffer into an array so I can get the locations of all the vertices.  (Eventually, I ...Show All

• Aerofluff Question on ID3DXEffect::SetArrayRange

  Hi, I'm currently adding shader instancing to our engine. After I changed the single world matrix in the effect file to a matrix array, I noticed a heavy performance drop. The fps went down by almost 30%. After some investigation I found that the fps changes with the size of the matrix array, so the effect framework seems to always copy all elements of the array, not only those that were actually set. I then wanted to optimize this using the ID3 ...Show All
