easy-opengl is a collection of utilities to make opengl app more quickly and easy without losing custumization and freedom.

Example

``` rust use easyopengl::buffers::*; use easyopengl::shader::; use easy_opengl::textures::;

const VERTEXSHADERSOURCE: &str = r#" #version 330 core layout (location = 0) in vec3 aPos; layout (location = 1) in vec2 aTexCoord;

out vec2 TexCoord;

void main() {
   gl_Position = vec4(aPos.x, aPos.y, aPos.z, 1.0);
   TexCoord = aTexCoord;
}

"#;

const FRAGMENTSHADERSOURCE: &str = r#" #version 330 core out vec4 FragColor; in vec2 TexCoord;

uniform sampler2D texture1;
uniform vec4 color = vec4(1.0);

void main() {
    FragColor = texture(texture1, TexCoord) * color;
}

"#;

pub struct Vertex { pub pos: [f32; 3], pub uv: [f32; 2], }

pub fn main() { let mut shader = Shader::new(); shader.loadfrommemory(VERTEXSHADERSOURCE, FRAGMENTSHADERSOURCE, None);

let vertices = vec![
    Vertex {
        pos: [0.5, 0.5, 0.0],
        uv: [1.0, 1.0],
    }, // top right
    Vertex {
        pos: [0.5, -0.5, 0.0],
        uv: [1.0, 0.0],
    }, // bottom right
    Vertex {
        pos: [-0.5, -0.5, 0.0],
        uv: [0.0, 0.0],
    }, // bottom left
    Vertex {
        pos: [-0.5, 0.5, 0.0],
        uv: [0.0, 1.0],
    }, // top left
];
let indices = vec![
    0, 1, 3, // first Triangle
    1, 2, 3, // second Triangle
];

let vao = VertexArray::new();
let _vbo = VertexBuffer::new(calc_bytes_size(&vertices) as isize, Some(&vertices));

vao.bind();

submit_vertex_attribs(&mut vec![
    VertexAttrib::new(VertexAttribType::Float3, false, "aPos".to_string()),
    VertexAttrib::new(VertexAttribType::Float2, false, "aTexCoord".to_string()),
]);

let _ibo = IndexBuffer::new(calc_bytes_size(&indices) as isize, Some(&indices));

let mut texture = Texture2D::new();
texture.load_from_file("./a.png", TextureConfig::new());

} ```
