Obliviengine

My dumb little renderer.

Compile OE

$ git clone --recursive https://github.com/TristanWellman/obliviengine
$ cd obliviengine
$ make

This should build the library that you can include in your project.

Copy the lib (and dlls), and include folders to your project

Sample Cube

---

sample.c

#include <OE/OE.h>

void draw() {
	OEDrawObject(OEGetObjectFromName("OECube"));
}

void event() {
	SDL_Event event = OEGetEvent();
	float camSpeed = 5.0f*OEGetFrameTime();
	if(OEIsKeyPressed()) {
		Vec3 pos = OEGetCamPos();
		switch(OEGetKeySym()) {
			case SDLK_w: OEMoveCam(FRONT, camSpeed); break;
			case SDLK_s: OEMoveCam(BACKWARD, camSpeed); break;
			case SDLK_a: OEMoveCam(LEFT, camSpeed); break;
			case SDLK_d: OEMoveCam(RIGHT, camSpeed); break;
			case SDLK_SPACE: OEMoveCam(UP, camSpeed); break;
			case SDLK_RSHIFT:
			case SDLK_LSHIFT: OEMoveCam(DOWN, camSpeed); break;
		};
	}	
}

int main(int argc, char **argv) {
	
	OEInitRenderer(1280, 720, "game", PERSPECTIVE);
	OEEnableDebugInfo();
	
	while(OERendererIsRunning()) {
		OEPollEvents((EVENTFUNC)event);
		OERenderFrame((RENDFUNC)draw);
	}
	
	return 0;
}

Compile

-Iinclude and -Llib can be replaced with whatever folders you are using.

gcc -g -Iinclude sample.c -o sample -Llib -lOE -lSDL2 -lgdi32 -lopengl32 -lm -ldl -lpthread

OpenXR-SDK

---

• To use VR with obliviengine simply install the OpenXR-SDK mingw package through msys2

$ pacman -S mingw-w64-x86_64-openxr-sdk

Program setup:

#include <OE/OE.h>
#include <OE/openxr/OEOpenxr.h>

void draw() {
	OEDrawObject(OEGetObjectFromName("OECube"));
}

void event() {
	SDL_Event event = OEGetEvent();
	float camSpeed = 5.0f*OEGetFrameTime();
	if(OEIsKeyPressed()) {
		Vec3 pos = OEGetCamPos();
		switch(OEGetKeySym()) {
			case SDLK_w: OEMoveCam(FRONT, camSpeed); break;
			case SDLK_s: OEMoveCam(BACKWARD, camSpeed); break;
			case SDLK_a: OEMoveCam(LEFT, camSpeed); break;
			case SDLK_d: OEMoveCam(RIGHT, camSpeed); break;
			case SDLK_SPACE: OEMoveCam(UP, camSpeed); break;
			case SDLK_RSHIFT:
			case SDLK_LSHIFT: OEMoveCam(DOWN, camSpeed); break;
		};
	}	
}

int main(int argc, char **argv) {
	
	OEInitRenderer(1280, 720, "game", PERSPECTIVE);
    OEInitOpenXR();
	OEEnableDebugInfo();
	
	while(OERendererIsRunning()) {
		OEPollEvents((EVENTFUNC)event);
        OEPollXREvents();
		OERenderXRFrame((RENDFUNC)draw);
	}
	
	return 0;
}
