How to resolve this JNI error when trying to run LWJGL “Hello World”?

由 别来无恙 提交于 2019-11-27 17:30:46
问题 I'm trying to run the sample "Hello World" from the LWJGL website From this link: LWJGL "Getting Started" I'm trying to do this via the command line, just so I understand the "behind the scenes" a bit better. I've managed to compile without any errors, but when I try to run the program I'm getting this error: C:\JavaProjects\LearningLWJGL>java -classpath .;./lib/*.jar -Djava.library.path=C:\Windows\System32 HelloWorld Error: A JNI error has occurred, please check your installation and try

What does the -XstartOnFirstThread VM Argument do / mean?

I can't find documentation for the VM argument -XstartOnFirstThread . Seems necessary for me to run JOGL through LWJGL on my Mac. What does it mean? It seems to be that some process wants thread 0. Is this correct? Please note: I have a run() method in my main class. It doesn't seem to be overriding anything and I'm not implementing runnable. Example source code I'm running here: http://www.lwjgl.org/guide As of Java 1.7.0_u4, this option is documented in java -X on the Mac OSX platform. The option causes the JVM to use thread 0 to start the application. Apparently this is necessary to get Mac

I'm working on a card game, and currently have a good foundation but I'm running into an error when I run it in eclipse. I'm also using slick 2d. Here is the error from the console.

Why is my OBJ parser rendering meshes like this?

由 北战南征 提交于 2019-11-27 05:13:35
I've taken it upon myself to add OBJ parser/importer support to a 3D rendering engine I've been working on. I've followed the specification found HERE nearly 'to a tee', with the current exception of limiting all support to groups, faces, vertices, normals and texture coordinates (so no material library or free-form poly support, as of yet). My goal was to simply parse line by line -- generating an object-oriented, hierarchical tree-like scene graph as I went along -- and allow the developer to automatically bind the data to a shader program with very few manual calls in order to start

LWJGL Textures and Strings

由 ╄→尐↘猪︶ㄣ 提交于 2019-11-27 01:52:56
问题 Is it possible to load PNG Textures and draw Strings in LWJGL WITHOUT using the Slick Framework? Everytime I google "how to load png images in lwjgl" I get answers like this -> "hey just use the textureloader from the slick framework" . Same for "how to draw strings in lwjgl" -> "just use the TTFFont Class from the slick framework" But I don't want to use this half-way-crossframework design. Because I don't think that this is the best way. Are there any Libraries or Extensions for LWJGL that

Converting quadriladerals in an OBJ file into triangles?

由 巧了我就是萌 提交于 2019-11-26 20:02:06
问题 At first, it seemed obvious... Make 2 triangles per face wherever 4 indices were found, right? Meaning, the following: v 1.000000 1.000000 0.000000 v -1.000000 1.000000 -0.000000 v 1.000000 -1.000000 0.000000 v -1.000000 -1.000000 -0.000000 f -4 -3 -2 -1 ... would, in turn, need to be converted into something like: v 1.000000 1.000000 0.000000 v -1.000000 1.000000 -0.000000 v 1.000000 -1.000000 0.000000 v -1.000000 -1.000000 -0.000000 f -4 -3 -2 f -2 -3 -1 This particular example, of course,
