MP3D Engine Alpha 33
Re: MP3D Engine Alpha 30
Menu: compiler -> compiler options. You will find a textfield called "Library Subsystem" here. Just type in "dx9" (there should be the same, if you open a demo file)

Re: MP3D Engine Alpha 30
thanks man and it work 
I got a questions...
You know Alien Breed Intro Demo where show all the 2D stars doing different directions and how I would do it knowing when the stars come toward me then change different directions like 3D World using Z Values and so on

Re: MP3D Engine Alpha 30
Hi firstly wonderful little addition to PureBasic, just a quick question.
Does the TileEngine support layers?
Example: you can create a map in 'Tiled' with many layers, however how do you code the TileEngine and insert this new layer.

Re: MP3D Engine Alpha 30
I don't know how MP3D handles Tiles and if it does layers like that, but I would hazzard a guess that even if it didn't, you could still do it if you:
Built a parser to read the file format into data you can feed to the tile engine.. Then draw the tiles in proper Z-order (bottom-most layer gets drawn first, next highest on top of that, next highest on top of that, etc)

Re: MP3D Engine Alpha 30
Hi applepi,
you have made nice demos and functions with the vertex / triangle functions. I hope you understand now the vertex and / triangle function ?!?
littel example:
A mesh has vertex points. The Vertex point has a xyz point in space and can have a color function and for textures a uv coordinate. You can have some of these vertexe in a mesh, but the only thing you see are the triangles of a mesh. A triangle is made from the position of 3 vertex points. Your mesh can have 1000 vertex, but you only see the created triangles:
for example a little demo of a 2d mesh with triangle creation

thank you very much

Re: MP3D Engine Alpha 30
Hi
while looking at the Michael example above i get an idea to make holes and tearing and destroying a mesh. since the mesh composed from triangles, what if we pick some triangle and then assign the coordinates of the second vertex the same as the third vertex, then we will have a very thin triangle ie a line and the what was before a triangle area now a void we can see through it.
here is an example to demonstrate that. just click on the green board to tear it and to see how light go through its holes.
the program depends on the MP3D example "MP_PickingTriangle.pb" inside picking folder, if you give the green board a real texture such as bricks or a tiger skin then we will have more amusing show.
the idea are not complete since it does not destroy triangles inside the mesh correctly, it is more correct at the corners of the board. but i present the example until i improve it more. also i want to put a moving sun to make it more enjoyable.
i hope the next version of MP3D to support shadow on resolution 640x480.

Re: MP3D Engine Alpha 30
in the previous example i was not able to make a hole in the middle of the green board correctly
here is a way to make a hole inside a mesh correctly
we use custom mesh made from adjacent independent triangles, so we can erase any triangle without affecting the others.
it is made from 18 triangles and the numbering of indexes for triangle 1 is
index 0 have coordinates 0,3,0
index 1 have coordinates 1,2,0
index 2 have coordinates 1,3,0
index 3 is for triangle 2 and begins with 0,3,0
look the figure below (not showing z coordinate because it is all 0)
(remember the triangle corners are corner 0, corner 1, corner 2)
when we want to delete triangle 9 we change the coordinates of corner 1 of the triangle 9 which have index 25 like this:
MP_VertexSetX(Mesh,25,2)
MP_VertexSetY(Mesh,25,2)
MP_VertexSetZ(Mesh,25,0)
ie we give it the coordinates of the triangle 9 corner 2 (index 26)
you can add more to MP_AddVertex such as MP_AddVertex(Entity, x.f, y.f, z.f [, Color [, u.f, v.f [, nx.f, ny.f, nz.f]]]) look docs
look example MP_UseVertex.pb in Mesh folder to see how to texture a mesh made using MP_AddVertex + MP_AddTriangle
click the mouse in the middle of the green board and you can erase triangles in the middle and the light will pass through it.

Re: MP3D Engine Alpha 30
hello applePi,
thanks for your great Demo. This bring me an Idea of two new commands. One Command to delete vertexe and one Command to delete Triangles. I will test id but i think In the next version i will make this new command.
For exampel
MP_FreeTriangle (mesh, triangleindex)
MP_FreeVertex (mesh, vertexindex)
If the command are ready i can give you a beta version for testing if you want...
Greetings Michael

Hi Michael
MP_FreeTriangle and MP_FreeVertex will be a great idea. i wish if it can be used also with the mesh created with MP_CreatePlane function
of course i will test the beta version when it is ready
thanks

some beautiful models
some math programs can export its 3D Graphics to 3D files formats such as 3ds format and can Import it again, such as mathematica v8 or above (http://www.wolfram.com/mathematica)
read this mht file which show how to do that in a one page tutorial :
https://sites.google.com/site/zak31415/ ... ormats.mht
also look here: http://reference.wolfram.com/mathematic ... phics.html for some examples
if you clicked at the codes lines a javascript will show a copyable text.
i have Exported some Graphics using mathematica and attached some small size models including a colorful helicopter and a pb example you can download it from here
http://www.mediafire.com/?19wok6r34g5p9oo
some notes:
1-the helicopter model are colored, i don't know how it is colored, but it is not a texture. when i have used MP_LoadMesh to load a "helicopter.3DS" it is not colored but shaded black and white. and when i have exported that 3DS file to directX x file using milkshape and using the MP_LoadMesh to load the "helicopter.x" now it show the color, i deduce that MP3D are more comfortable with x files than 3DS files.
2- the mathematica Export the models without textures and some times the models have a color, so we have to texture the models using other programs.

Re: MP3D Engine Alpha 30
Hi applePi ,
nice idea to use mathematica for a model...
The 3ds and b3d import modul is written myself. I will have a look on it an perhaps i find a solution. You can color a mesh with textures and you can give every vertex point a different color and the vertex color colored the triangle. I thing in this case the 3ds model ist colored with a vertex color and the import could not read this.

Re: MP3D Engine Alpha 31
Update auf Alpha 31
Works only with PB 4.61 (x86 and x64) or higher
* Some Updates and new demos
* New command expansions
* you can change Pixel of textures
* Anti Alaising function
* Particlefunktion has big expansions
* More and usefull Triangel and Vertex functions

Working on - MP3D Library - PB 5.73 version ready for download
Re: MP3D Engine Alpha 31
thank you Michael for the new version.
the new funtion "MP_SaveMesh" which save the model to x format makes MP3D a kind of a modelling program .
as a proof for the new users here is a program to create a sphere click on it to make holes in it then when we exit the program will save the mesh as a model.x . just save first the texture http://s15.postimage.org/c6q54l4tn/texture.png to the same folder.
now run the second program to load the model.x file and you will see the model with the holes you have made. open the model.x file with any modelling software to view it textured
PS:
i have found also that we can save the models transformed mathematically into model.x , this is great and resembles what an expensive wolfram mathematica program do, we design klein bottle or mobius strip mathematicaly and save it to model. as an example the deformation example in :MP3D Demos\Mesh>MP_Bewegende Objekte.pb we wait 10 seconds after enough deformation and save the model, we open it in milkshape and waw it is a real model deformed.
try the example modified to save the model after 10 seconds and exit. if i don't want to use MP3D then this feature alone will force me to use it for making mathematical models.
look the mathematically constructed "A model" here: http://www.purebasic.fr/english/viewtop ... 20#p383932
just insert MP_SaveMesh("A_model.x",plane) after the latest "wend" and when you exit it will save a splended textured 3D A letter, i have opened it in milkshape and saved it as 3ds file. here is the result of the A_model converted by milkshape to textured 3ds file
thank you Michael for this great feature.
PS-2: if i install v 31 on a fresh purebasic then when we run mp3d program an error message file not found d3d9.lib ,Dinput8.lib and so on. but if we install v 30 before then v 31 it will work
