Web Application to Draw 3d objects on images

Required knowledge: webgl, [login to view URL], math, 3d vector I would like to launch a competitor to [login to view URL] Watch the following videos: BETA [login to view URL] LIVE [login to view URL] CALIBRATION: [login to view URL] Aside from the web component, this job requires the use of perspective projection, see: [login to view URL] Calibrating and rendering 3d objects is important. For this fixed-price job, the UI can be bootstrapped, without custom design. Just need a clean responsive layout with white background. There should be a way to add 3d models to the collection, which is able to link and download more 3d models from URL (*.3ds format). The webpage should support any amount of items. Tools to convert *.3ds format to [login to view URL] already exist. See [login to view URL] The import tool needs to support name, category, tag and type of object (wall, surface, floor, hanging). I would like to use models from [login to view URL] for use on this site. This is a fixed price job. It needs to be functionally equivalent to the referenced competitor. This includes webkit compatibilty (safari, chrome), rotating objects and moving objects up/down. Once app is complete and delivered, possibility to hire full time. Only developers with a strong desire to progress and have a long-term work relationship should apply. To apply for this job, please choose one of the two problems and give an answer in your proposal: Problem A We have an arc represented by three points in two dimensions. Two points (A, B) are endpoints of the arc. The third point (C) is at the intersection of the arc and the perpendicular bisector of the line defined by A and B. Question: Write the pseudocode to approximate the arc using line segments. Problem B Given a point P and a triangle made from three points (A, B, C) in three dimensions, we are interested in an efficient way to determine the point on plane ABC, inside of triangle ABC, which is closest to P. Question: Write the pseudocode to calculate the point inside of ABC which is closest to P.
