I just started doing some development with JOGL. I am fairly experienced with OpenGL, but this is my first time using JOGL.
I can run the WebStart VBO demo, so I’m confident that my environment is not the issue.
I am trying to create multiple rendering paths for a game engine, but I’m stuck on my VBO implementation. The JVM exception is being thrown when I try to call glDrawElements, but I’m not sure if it’s a setup error, or an error when I try to draw. All of my code is Scala, so instead of posting the code, I’ll post the DebugGL2 output (which is a fantastic feature by the way).
Creating my Vertex Array VBO. There is some logic in here to make sure my buffer got copied correctly to video memory (The line between glMapBuffer and glUnMappBuffer is a check to make sure all of the data is the same after I copy it over)
glGenBuffers(<int> 0x1, <[I>, <int> 0x0)
glBindBuffer(<int> 0x8892, <int> 0x1)
glBufferData(<int> 0x8892, <int> 0xC0, <java.nio.Buffer> java.nio.DirectFloatBufferU[pos=0 lim=48 cap=48], <int> 0x88E0)
glMapBuffer(<int> 0x8892, <int> 0x88B8) = java.nio.DirectByteBuffer[pos=0 lim=192 cap=192]
Float Buffer data: (0,true)(1,true)(2,true)(3,true)(4,true)(5,true)(6,true)(7,true)(8,true)(9,true)(10,true)(11,true)(12,true)(13,true)(14,true)(15,true)(16,true)(17,true)(18,true)(19,true)(20,true)(21,true)(22,true)(23,true)(24,true)(25,true)(26,true)(27,true)(28,true)(29,true)(30,true)(31,true)(32,true)(33,true)(34,true)(35,true)(36,true)(37,true)(38,true)(39,true)(40,true)(41,true)(42,true)(43,true)(44,true)(45,true)(46,true)(47,true)
glUnmapBuffer(<int> 0x8892) = true
Creating my Color Array VBO. This is the same exact logic as when I create the Vertex Array VBO
glGenBuffers(<int> 0x1, <[I>, <int> 0x0)
glBindBuffer(<int> 0x8892, <int> 0x2)
glBufferData(<int> 0x8892, <int> 0xC0, <java.nio.Buffer> java.nio.DirectFloatBufferU[pos=0 lim=48 cap=48], <int> 0x88E0)
glMapBuffer(<int> 0x8892, <int> 0x88B8) = java.nio.DirectByteBuffer[pos=0 lim=192 cap=192]
Float Buffer data: (0,true)(1,true)(2,true)(3,true)(4,true)(5,true)(6,true)(7,true)(8,true)(9,true)(10,true)(11,true)(12,true)(13,true)(14,true)(15,true)(16,true)(17,true)(18,true)(19,true)(20,true)(21,true)(22,true)(23,true)(24,true)(25,true)(26,true)(27,true)(28,true)(29,true)(30,true)(31,true)(32,true)(33,true)(34,true)(35,true)(36,true)(37,true)(38,true)(39,true)(40,true)(41,true)(42,true)(43,true)(44,true)(45,true)(46,true)(47,true)
glUnmapBuffer(<int> 0x8892) = true
Creating the VBO for my face indices.
glGenBuffers(<int> 0x1, <[I>, <int> 0x0)
glBindBuffer(<int> 0x8893, <int> 0x3)
glBufferData(<int> 0x8893, <int> 0x40, <java.nio.Buffer> java.nio.DirectIntBufferU[pos=0 lim=16 cap=16], <int> 0x88E0)
glMapBuffer(<int> 0x8893, <int> 0x88B8) = java.nio.DirectByteBuffer[pos=0 lim=64 cap=64]
Int Buffer data: (0,true)(1,true)(2,true)(3,true)(4,true)(5,true)(6,true)(7,true)(8,true)(9,true)(10,true)(11,true)(12,true)(13,true)(14,true)(15,true)
glUnmapBuffer(<int> 0x8893) = true
Disabling VBOs
glBindBuffer(<int> 0x8892, <int> 0x0)
glBindBuffer(<int> 0x8893, <int> 0x0)
Rendering
glBindBuffer(<int> 0x8892, <int> 0x1)
glEnableClientState(<int> 0x8074)
glVertexPointer(<int> 0x3, <int> 0x1406, <int> 0x0, <long> 0)
glBindBuffer(<int> 0x8892, <int> 0x2)
glEnableClientState(<int> 0x8076)
glVertexPointer(<int> 0x3, <int> 0x1406, <int> 0x0, <long> 0)
glBindBuffer(<int> 0x8893, <int> 0x3)
glDrawElements(<int> 0x0, <int> 0x10, <int> 0x1405, <long> 0)
The error occurs in the glDrawElements method, and it is a JVM error.
