c++ - Why not call nullptr NULL? -


in c++11 nullptr keyword added more type safe null pointer constant, since previous common definition of null 0 has problems.

why did standards committee choose not call new null pointer constant null, or declare null should #defined nullptr?

stephan t. lavavej (member of c++ standard committee) explained once in talk (55:35):

while implementation allowed #define null nullptr, break quite uses like

int = null;

and apparently there plenty of those. not force change.

c# - SharpDX Toolkit models rendering inside out -

a little while ago decided switch xna sharpdx toolkit actively being supported , quite similar xna. while i've had no trouble @ creating 2d games decided attempt basic 3d game. can both model , it's texture load when renders shows texture on side facing away camera doesn't show @ in between. this code using set environment. vector3 cameraposition = new vector3(0, 0, -10f * 2.5f); vector3 cameratarget = vector3.zero; boundingsphere modelbounds = model.calculatebounds(); float fovangle = mathutil.degreestoradians(45); float aspectratio = (float)graphicsdevice.backbuffer.width / graphicsdevice.backbuffer.height; float near = 0.01f; float far = 100f; float scaling = 10f / modelbounds.radius; matrix translation = matrix.scaling(scaling) * matrix.rotationy((float)gametime.totalgametime.totalseconds) * matrix.translation(0, -modelbounds.center.y * scaling, 0); matrix lookat = matrix.lookatlh(cameraposition, cameratarget, vector3.u...
