Shaderific vs SimplexLP

Get started with OpenGL ES 2.0 and OpenGL ES 3.0 shader development on your iPad, iPhone or iPod touch today. Create your own vertex and fragment shaders using the OpenGL Shading Language (GLSL) and compile them on your mobile device. Tweak your shader code and the values of the uniforms and see the effects immediately. Wether you are an experienced developer or a beginner, Shaderific is a powerful and fun tool to work on your shaders on the go or to do some prototyping on the couch. GLSL REFERENCE - Built-in reference for the OpenGL Shading Language - Detailed descriptions of all GLSL data types, qualifiers, variables, constants, statements and functions - Context-sensitive help for all GLSL keywords providing a description and usage examples (iPad) EDITOR - Code completion for keywords, functions and user-defined variables (on pressing the tab key) - Syntax highlighting with customizable colors - Line numbers and error highlighting - 9 fonts in 9 sizes (6 monospaced, 3 proportional) - Three customizable predefined themes (default, light, dark) - Keyboard extension with frequently used keys on iPad - Improved undo / redo support SHADERS - 28 built-in shaders ranging from simple lighting and procedural coloring to normal mapping and procedural noise generation - Change the values of the built-in parameters and uniforms without interrupting the render loop and see the effects immediately - Import shader files with Dropbox or iTunes Document Sharing OBJECTS - 30 objects including 3 polygons, 6 polyhedrons, 7 parametric surfaces and 14 real-life items (teapot, watering can, chair, trumpet, etc.) - Resolution of real-life objects ranges from 500 to 300,000 faces (triangles) - Resolution of the parametric surfaces can be changed to see how this affects the quality of the rendered object - Import objects in the Wavefront object format (.obj files) - Export objects as header files DRAW INSTANCED Draw multiple instances of the same object using the newly introduced functionality PARTICLE SYSTEMS - Particle systems with spherical and cubic shape - Adjustable number of particles between 1,000 and 100,000 TEXTURES - 26 textures including 4 patterns, 4 earth maps, 6 normal maps and 2 cubemaps - Import textures in JPEG, PNG, TIFF, GIF and BMP format - Import supports texture2D textures as well as cubemaps FRAMEBUFFER TEXTURE Framebuffer texture containing the previously rendered frame STEREOSCOPY Anaglyph 3D red-cyan rendering option for all shaders VIDEO SUPPORT - Camera texture with video stream from the built-in cameras - Uniform with face bounds for up to 5 faces (face detection) - Movie textures with imported movie files - Video recording with automatic export to the photo library FULL SCREEN MODE - Full screen mode for image processing (e.g. texture blending) - Hiding the menu and status bar on double tap MULTITOUCH SUPPORT - Multitouch support with a uniform array in the shader programs - Coordinates for up to 10/5 simultaneous touches on iPad/iPhone DROPBOX SUPPORT - Import / export shader files - Import objects (Wavefront .obj files) - Import textures (jpeg, png, tiff, gif, bmp) - Import movies (m4v) - Export objects as header files with vertex, normal and face data PHOTO LIBRARY - Import images / movies - Export recorded videos FILE SHARING - Open shader files in other iOS apps - iTunes Document Sharing EXTERNAL KEYBOARD Full support for external bluetooth keyboards SETTINGS (PARAMETERS AND UNIFORMS) The built-in parameters and uniforms can be changed in the settings menu without interrupting the render loop. Parameters: - Frame rate - Scaling - Object resolution (parametric surfaces) - Number of particles (particle systems) - Number of instances (draw_instanced) - Video resolution - Video playback frame rate - Stereo anaglyph red-cyan - Stereo intensitiy - Global rotation (axis and velocity) - Object rotation (axis and velocity)

SimplexLP solves linear optimization problems, which can be mathematically described with an objective function and a set of constraints. With the new graphical representation (possible with 2 variables only) it is a lot easier to understand the theoretical concept of linear optimization! SimplexLP is the perfect learning companion for teachers (to set up problems) and students (to learn the Simplex algorithm). It is very easy to change coefficients and see how the solution varies. For the calculation the famous Simplex algorithm is used. With SimplexLP you can: – easily set up the objective function and the constraints; – solve maximization and minimization problems; – solve problems with unlimited number of variables and constraints; – solve problems with ≤, ≥ and = (in)equalities; – get all the possible solutions ("edges") to a problem; – get accurate calculations with fractions; – get your output in fractions or decimal values; – set a fixed value in the objective function, e.g. for fixed costs; – set the tab width (via a simple swipe gesture) to format the tableaus; – get a graphical representation of optimization problems with 2 variables. With SimplexLP linear optimization really makes fun!
