wpf allows specify linear affine transform on graphical objects. can translation, rotation, scaling, skewing, or combination of that. can specify 2x3 matrix. what want perspective transform in 2d space, requires 3x3 matrix, , known photoshop or gimp, can drag 4 corners of image independently. i tried use 3d features of wpf, set viewport3d , orthographiccamera , placed (2d) objects onto xy-plane. but i'm wondering if there no easier way accomplish perspective transform in wpf? i'm asking because i'd perspective transform on text: in 2d can use textblock , in 3d gets more compliacted, i'd have create brush out of geometry out of formattedtext . as can read here there 3rd party libraries implement silverlight's planeprojection wpf. otherwise forced code yourself.

i'm trying move skspritenode in arc physics in spritekit so: but unsure physic should apply (applyimpulse, applyforce, applytorque). currently using applytorque, code not work, , produces no movement on object: _boy.physicsbody.velocity = cgvectormake(1, 1); cgvector thrustvector = cgvectormake(0,100); [_boy.physicsbody applytorque:(cgfloat)atan2(_boy.physicsbody.velocity.dy, _boy.physicsbody.velocity.dx)]; applytorque not right method this. torque twisting force causes node rotate around center point. there no 1 easy command looking do. fail mention method of movement node. apply force, impulse, etc... going have come hack one. the sample project below looking , point in right direction. going have modify code suit specific project's needs though. tap/click screen once start moving node , tap/click screen second time start 90 degree movement change. #import "gamescene.h" @implementation gamescene { int touchcounter; bool changedir...
