This library is to simplify opengl-usage for 2D rendering and to easy
handle procedural shadercode and imagedata from texture-atlases.

It's written in Haxe and runs multiplatform with Limes GL-context and environment.

haxelib git peote-view https://github.com/maitag/peote-view

• runs native on linux/bsd/windows/android, neko/hashlink-vm, javascript-webbrowser (macOS and iOS should run but not much tested yet)

• can be compiled for a special OpenGL version (ES 2/3 - webgl 1/2) or with version-detection at runtime

• optimized to draw many elements thats sharing the same shader and textures

• simple usage of textureatlases (parted into slots and tiles)

• multitexture usage per shader

• supports shadertemplates and opengl-extensions

• simple formula- and glslcode-injection

• animation by gpu transition-rendering of vertexattributes

• opengl-picking for fast detection of elements that hits a point at screen

• renderToTextures (framebuffer)

• ...

PeoteView

• main screenarea that contains all Displays
• zoom- and scrollable

Display

• rectangle area inside the View (using gl-scissoring for masking)
• contains Programs to render
• zoom- and scrollable
• content can be rendered into a texture

Element

• rectangle graphics like Sprites
• can have position, size and many other kind of attributes to render inside displayarea
• different types of Element-classes with rquivalent shadertemplate is macro-generated by meta-data
• only properties/shaderattribures that is need will be generated (to have optimized types of Elements for any purpose)

Buffer

• depends on type of generated Element
• stores many Element-instances to build up an equivalent gl-vertexbuffer
• can be dynamically grow/shrink
• using fast opengl instance-drawing for all contained Elements
• can be bind to one or many Programs

Program

• combines Textures and shadercode for one Buffer
• can use formulas for fragmentshader to compose Texturedata
• can use formulas to change other attributes inside shader
• can inject GLSL-code directly into shader

Texture

• to store imagedata or textureatlases
• can be splitted into Slots to store many images, calculates best size for gl-texture
• Slots can be parted into Tiles

TextureCache

• handle multiple textures, imageloading and texture reusage

• better Readme, more documentation and api-generation
• better texture/imagehandling and more texture-colortypes
• better blendmode handling
• z-depth via texture-channel
• normal-mapping
• uv-mapping
• multiwindows (did not work with textures yet)
