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();
