This freeware TPC library gives you access to low-level vertex manipulation and to some object and camera properties.

Command list.

Return Float=DK GET CAMERA ASPECT(Camera Number)
DK CONVERT 3D TO 2D Camera Number, X, Y, Z

Planned commands in shareware version:

Basic3D

Return Float=ADVANCED INTERSECT OBJECT(Object Number, X, Y, Z, ToX, ToY, ToZ)
Return Integer=PICK OBJECT(Camera Number, Screen X, Screen Y, Object Start, Object End)
Return Integer=GET PICK POLY()
APPLY MATRIX4 TO LIMB Object Number, Limb Number, Matrix4

Matrix

Return Float=Intersect Matrix(MatrixNum, X, Y, Z, ToX, ToY, ToZ)
Return Integer=Pick Matrix(CameraNum, Screen X, Screen Y, Matrix Start, Matrix End)
Convert Matrix To Object MatrixNum, ObjectNum

3DSprite

Make Object 3DSprite ObjectNum, X, Y, Width, Height
Text In 3DSprite 3DSpriteNum, X, Y, Text$
Line In 3DSprite 3DSpriteNum, X1,Y1,X2,Y2
Dot In 3DSprite3D SpriteNum, X, Y
Paste Image In 3D3DSprite, SpriteNum, X, Y, ImageNum
Box In 3DSprite 3DSpriteNum, Left, Top, Right, Bottom
Point In 3DSprite 3DSpriteNum, X, Y
CLS In 3DSprite 3DSpriteNum
Resize 3DSprite 3DSpriteNum, X, Y, Width, Height
Return Integer=3DSprite Width(3DSpriteNum)
Return Integer=3DSprite Heigth(3DSpriteNum)
Return Integer=3DSprite Position X(3DSpriteNum)
Return Integer=3DSprite Position Y(3DSpriteNum)
Return Integer=3DSprite Depth(3DSpriteNum)
Return Integer=Pick 3DSprite(CameraNum, Screen X, Screen Y, 3DSprite Start, 3DSprite End)

P.S. Sorry for my English.

keyword file missing.

Dmitry,

I think the command nemes are just fine. They are very self explanatory. Looks like a very nice plugin!

Yes, and it'll make DrakeX happy because he's been asking for low level vertex manipulation functionality for ages.

Philip

me and wolf can enhance our memblock terrains now. once that little command is fixed.

Hmm... not sure if that speed drop is encouraging.
how exactly are you getting around not locking and unlocking the vertex buffer?

I have fixed some bugs with Set Vertex... commands.

New examples for updated TCP. http://www.dannywartnaby.co.uk/rgt/attachments/LowLevVertExamples.zip

Added few more commands for Camera3D. All of them work well with scaled viewports and multiple cameras.

Return Float=DK GET CAMERA FOV(Camera Number)
Return Float=DK GET CAMERA NEAR(Camera Number)
Return Float=DK GET CAMERA FAR(Camera Number)
Return Integer=DK GET CAMERA VIEW X(Camera Number)
Return Integer=DK GET CAMERA VIEW Y(Camera Number)
Return Integer=DK GET CAMERA VIEW WIDTH(Camera Number)
Return Integer=DK GET CAMERA VIEW HEIGHT(Camera Number)
Return Float=DK GET CAMERA ASPECT(Camera Number)
DK CONVERT 3D TO 2D Camera Number, X, Y, Z
DK CONVERT 2D TO 3D Camera Number, X, Y, Distance

Post away if you have any suggestions for additional features of this TPC library.

this is a REALLY impressive TPC!!!! fantstic work!!

I have decided to rename library to DKShop and release it in the current condition as freeware. All other works above additional commands will proceed above the shareware version.

Dmitry,
Can I ask, how did you access this information? Did you find out where the object data is stored in memory from withing DBP?

Or did you decompile the old dll's for DBP and just mimik their commands?

Just curious, as I have often wondered how you would find where in memory the object data is stored

PS figured I'd post here so I didn't mess up your Prog Announcememnt thread

Jess.

?GetInternalData in DBProBasic3DDebug.dll return a pointer on object data. Same thing with ?GetInternalData in DBProCameraDebug.dll.

more importantly, how did you figure out the data format? are they using a standard DirectX struct, or something custom... I'd love to know how you figured that part out!!

Ah, damn, that simple eh?

Well, it's nice to know that you figured it out

Good job.

Jess.

Something custom. I asked Mike about internal structure of object, but he has not answered me. So I decompiled dll, and began to search for the information on structure of object data. I hope in the near future TGC will give us full SDK.

I'd like to get to know all this deep 3D functions stuff. Am I right in thinking that using vertex buffers will be faster than the other method? If anyone can supply some example code I'd be grateful, particularly for getting vertex position data from an objects vertices. For example, morphing from one object to another (say 2 cubes with identical vertex count), which approach would be best, the DK commands or the VB ?
