if this is still active, send one to me also, my mail is in profile
I have radeon x800

Hi

I've just mailed it.
Copy it to any folder, create a java project (JCreator/Eclipse/whatever), link the project to LWJGL and ur good to go.

u can change in Main.Java:

1	m_heightMap.loadHeightmap2("Data/tavor64x64.jpg", // Load Our Heightmap

if u change the filename u can load other Heightmaps from any picture format.
some lines below u can change also the texture file.
u can also modify other params. enjoy

2	Java Game APIs & Engines / OpenGL Development / need small help with gl12.glDrawRangeElements(...)	on: 2007-03-08 14:04:43
in GL12.glDrawRangeElements(int mode, int start, int end, int count, int type, long indices_buffer_offset) can someone please explain what every parameter specifies? im not sure i got it right and i couldn't find any useful into in google/other. Lets say i have an indices buffer (size 6 = 2 triangles X 3 vertices) and 6 interleaved vertices in my vertices array (V[3]N[3]C[4]T[2]) of float type. what do i need to specify in glDrawRangeElements(...) to draw them all (its VBO based).

Hi I've just finished working on my port for NeHe lesson 45. since my video card sucks, i would like to have some people here testing it before i send it. i'll zip and send it to whoever leaves his email here. thanks

5	Java Game APIs & Engines / OpenGL Development / Re: A bug in Wiki-LWJGL tutorial?	on: 2007-03-01 12:20:59
sorry, it would be 4*(3+3). in any case it should not be (3+3+2) ....

Java Game APIs & Engines / OpenGL Development / Re: A bug in Wiki-LWJGL tutorial?

on: 2007-03-01 12:20:05

sorry, but i insist

the structure should be
V[3*4byte]N[3*4byte]C[4*4byte]T1[2*byte]

so if i need the texture (s,t) , i need to do :

1 2	intlvdarr[4(3+3+4)+0] = texture_s; intlvdarr[4(3+3+4)+1] = texture_t;

the texture offset WOULD be 3+3+2 for the following structure:
V[3*4byte]N[3*4byte]T1[2*byte]C[4*4byte]

please check it again Wink

thanks.

if someones wants, i can send him. thanks.

8	Java Game APIs & Engines / OpenGL Development / Re: A bug in Wiki-LWJGL tutorial?	on: 2007-02-27 12:03:05
yes, i understand what the x4 means, but if u decided that the interleaved structure is like this: V[xyz]N[xyz]C[rgba]T1[st] then the offset for the starting of the texture should be (3+3+4)4 and not (3+3+2)4, since the color have rgba channels = 4 channel..., and it comes before the texture channels... btw - i already implemented it, and its 3+3+4. please check ur tutorial again (it really helped me, though !).

Java Game APIs & Engines / OpenGL Development / A bug in Wiki-LWJGL tutorial?

on: 2007-02-26 23:52:16

Hi,

I've checked out the speedy VBO in
http://lwjgl.org/wiki/doku.php/lwjgl/tutorials/opengl/speedyvbo#interleaving_a_vbo

and I've notived that:

1 2	// texture coordinates offset = (3 + 3 + 2) * 4; GL11.glTexCoordPointer(2, GL_FLOAT, stride, offset);

Looks a little bit strange... shouldn't it be offset = (3 + 3 + 4) * 4 instead?

Anyway, i've solved my bug problems... it was all due to an unupdated driver of my laptop, and apperantly, now i DO have VBO supported... yey!

10	Java Game APIs & Engines / OpenGL Development / Need a reference code for glDrawElements	on: 2007-02-24 18:25:10
Hi all Im still having problems with using the buffers. I could not find any source that explains simply how to use them currectly with GL (thanks for all the links.. they did not help though). I need a reference code for using LWJGL with glDrawElements (non VBO please!). an app that is using GL_VERTEX_ARRAY,GL_TEXTURE_COORD_ARRAY and GL_COLOR_ARRAY would be best. please mail me to preshel@gmail.com thanks !

11	Java Game APIs & Engines / OpenGL Development / Re: Using DevIL to make a heightmap from a bmp/jpg file	on: 2007-02-17 21:25:51
Thanks anyway, I've figured it out i think. I just keep getting that annoying runtime bug again and again.

12	Game Development / Performance Tuning / Re: Making multiple TriangleStrips Vs. one long Triangle array	on: 2007-02-17 21:12:40
Im using glDrawArrays, and I haven't seen any "index pointer" yet. I would also like to enable VBO. Is there a way to upload the index array to the card's memory?

Game Development / Performance Tuning / OutOfMemoryError: Direct buffer memory

on: 2007-02-15 17:06:33

Hi, i've made:

1
2
3

         m_vertices = BufferUtil.newFloatBuffer(m_vertexCount * 3* fVertexPerPixel);      
        m_texCoords = BufferUtil.newFloatBuffer(m_vertexCount * 2* fVertexPerPixel);
        // float [] vertices= new float[m_vertexCount * 2* fVertexPerPixel*fVertexPerPixel];

and i get the memory error.
if i enable "float [] vertices= new float[m_vertexCount * 2* fVertexPerPixel*fVertexPerPixel];"
and disable "m_vertices = BufferUtil.newFloatBuffer(m_vertexCount * 3* fVertexPerPixel);", i dont get an error.

1) is the ByteBuffer limited in any way, and have less mem space than the java heap?
2) can i extend the java heap?

14	Game Development / Performance Tuning / Making multiple TriangleStrips Vs. one long Triangle array	on: 2007-02-15 14:49:05
Hi I am making something regarding a heightmap. well, i have the grid, and I want to use "GL_ARRAY_BUFFER" option (i dont have VBO on my laptop card ). I can make one long buffer of all my triangles, but I can also arrange my grid as a collection of triangle strips. What is considered to be faster? I can have just one single call for an ordinary triangle array, and I can have multiple calls for my multiple triangle strips. whats usually faster and regarded as better method?

Java Game APIs & Engines / OpenGL Development / Re: Using DevIL to make a heightmap from a bmp/jpg file

on: 2007-02-15 10:48:05

There is no book in DevIL, i guess.
for example, when i see on the documentation:
ilIsValid(int Type, java.lang.String FileName)
I dont know what is it for, what is "Type" param and which constant values are valid for it, etc.

anyhoo, i've got the following code:

1
2
3
4
5
6
7
8

        IntBuffer image = BufferUtil.newIntBuffer(1);
        IL.ilGenImages(image);
        IL.ilBindImage(image.get(0));
        IL.ilLoadImage("Data/heightmap1.bmp");
        IL.ilConvertImage(IL.IL_RGB, IL.IL_BYTE);
        ByteBuffer scratch = IL.ilGetData();
        for (int i=0;i<500;i++)
                 System.out.println(""+i+": "+scratch.get(i));

why do i see negative numbers on the output?

Usually when i'm reading something about a new library, I dont fully understands. Also, the DevIL documentation practictly dont exists. Just have the methods, and not how to use them. I looked up for the "imageio" , and i found it, but i could not figure out what to do with it... "image stream" etc. dont mean nothing to me. maybe i have a deeper problem. How do u guys understand such concepts?

17	Java Game APIs & Engines / OpenGL Development / Re: Using DevIL to make a heightmap from a bmp/jpg file	on: 2007-02-14 10:49:36
No. First, I dont even know in which library it is, and where is the documentation. Second, Why using some library, when DevIL exists? I just dont understand how to implement DevIL for my needs.

18	Java Game APIs & Engines / OpenGL Development / Re: Using DevIL to make a heightmap from a bmp/jpg file	on: 2007-02-13 21:02:47
Im a newbie... what is an "imageio" and how to use it to load bmp/jpg images?

Saying that stuff work in jogl doesn't actually mean anything. Since jogl and lwjgl are two completely different codebases you can't compare them in that regard. hi the display was created. I copy pasted a legitimate code from texture-loading in LWJGL based NeHe lesson 7....

Isn't jar a package? anyway, i pushed all the class files of myUtilities package into a jar file, and i've included it in the main jar file. still doesn't work. im TOTALLY lost. my app is very light weight... maybe i can send it to someone who is ready to make a batch file? i guess that i'll learn the rest by myself... I can also describe the structure of my files etc., if it will do any good.

Sorry to say, but im way too newbie to understand what to do with all that code, in order to do what i wanted (in the subject line).

It shouldn't crash, since the Nehe tutorial (45) worked with JoGL library. I just tried to port it to LWJGL, and it crashed when calling to GL11.glGenTextures(m_textureId). m_textureId is defined as: private IntBuffer m_textureId = ByteBuffer.allocateDirect(4).order(ByteOrder.nativeOrder()).asIntBuffer(); I just copy pasted all that memory stuff from other Nehe - LWJGL lesson, since it worked there (a textured spinning cube).

Quote from: Kova on 2007-02-12 12:50:06 ah the pain... use a manifest file, it's nicer way to create jars with manifest. Put your LWJGL jar into your jar file like any other file. Then you need to add class path argument into manifest file to your LWJGL jar file. This is example how I did it when I worked with jdbc driver: Ok, I did something else, and it worked , but now i have a totally new bug i have a "java.lang.NoClassDefFoundError" on one of my package classes. the package is defined as a class path in my manifest file as: Class-Path: myUtilities the app crashes when i try to call one of myUtilities classes from my main class. what can it be?

Hi... ok, i did what u suggested, and it worked, but now i have a serious runtime crash - # # An unexpected error has been detected by HotSpot Virtual Machine: # # EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x69557dda, pid=3168, tid=3156 # # Java VM: Java HotSpot(TM) Client VM (1.5.0_09-b03 mixed mode, sharing) # Problematic frame: # C [nvoglnt.dll+0x57dda] # # An error report file with more information is saved as hs_err_pid3168.log # # If you would like to submit a bug report, please visit: # http://java.sun.com/webapps/bugreport/crash.jsp # what can it be?

Java Game APIs & Engines / OpenGL Development / NullPointerException after calling to GL11.glGenTextures

on: 2007-02-11 22:20:06

I have the following code:

1 2	IntBuffer textureId = BufferUtil.newIntBuffer(1); GL11.glGenTextures(textureId); //

and i get a NullPointerException ...

why is that?

Java Game APIs & Engines / OpenGL Development / Extention query

on: 2007-02-11 21:49:47

i saw that JoGL can make the following code:

1
2
3
4

boolean has VBO = (gl.isFunctionAvailable("glGenBuffersARB") &&
                                                gl.isFunctionAvailable("glBindBufferARB") &&
                                                gl.isFunctionAvailable("glBufferDataARB") &&
                                                gl.isFunctionAvailable("glDeleteBuffersARB"));

what is the equvalient procedure in LWJGL?
