Shader-Wrapper

C++ Shader class to use in all platforms

1. Ceate vsh and fsh files (if not created yet)
2. Edit "glShaderHeader.h" for attributes and uniforms
3. Add "glShaderHeader.h" to your implementation class
4. Load sources of vertex and fragment shader
5. Create an instance of shader class "glShaderWrapper.h" and use it

Load files in objective-c

NSString *vshPath = [[NSBundle mainBundle] pathForResource:@"template" ofType:@"vsh"];
const char *vshSource = [[NSString stringWithContentsOfFile:vshPath encoding:NSUTF8StringEncoding error:nil] UTF8String];
NSString *fshPath = [[NSBundle mainBundle] pathForResource:@"template" ofType:@"fsh"];
const char *fshSource = [[NSString stringWithContentsOfFile:fshPath encoding    :NSUTF8StringEncoding error:nil] UTF8String];

Load shader

glShaderWrapper loadShader = glShaderWrapper(vshSource, fshSource);

loadShader.bindAttributeLocation(ATTRIB_VERTEX, "position");    // 1
loadShader.bindAttributeLocation(ATTRIB_COLOR, "color");        // 1

loadShader.link();                                              // Link shader

GLuint position = loadShader.attributeLocation("position");   // Optional get attribute location
GLuint color = loadShader.attributeLocation("color");         // Optional get attribute location

uniforms[U_MV_PROJ_MTX] = loadShader.uniformLocation("modelViewProjectionMatrix");  // Get uniform location

loadShader.use();                                               // Use shader

###FAST IMPLEMENTATION Copy and paste

include "glShaderHeader.h"

NSString *vshPath = [[NSBundle mainBundle] pathForResource:@"template" ofType:@"vsh"];
const char *vshSource = [[NSString stringWithContentsOfFile:vshPath encoding:NSUTF8StringEncoding error:nil] UTF8String]; 
NSString *fshPath = [[NSBundle mainBundle] pathForResource:@"template" ofType:@"fsh"]; 
const char *fshSource = [[NSString stringWithContentsOfFile:fshPath encoding:NSUTF8StringEncoding error:nil] UTF8String];

//LOAD SHADER
glShaderWrapper loadShader = glShaderWrapper(vshSource, fshSource);
loadShader.bindAttributeLocation(ATTRIB_VERTEX, "position");
loadShader.bindAttributeLocation(ATTRIB_COLOR, "color");
loadShader.link();
GLuint position = loadShader.attributeLocation("position"); //Optional
GLuint color = loadShader.attributeLocation("color"); //Optional
uniforms[U_MV_PROJ_MTX] = loadShader.uniformLocation("modelViewProjectionMatrix");
loadShader.use();
