algorithm - Java 2D Shading / Filling -

-

i have created "blob" bezier curves (screenshot below) , shade in such way appears pseudo-3d, darker shading on "left" edges , lighter on "right" edges, , perhaps pure white "light spots" on surface itself. example: i'd interested in how achieve shading used in this video.

  • can recommend way achieve this? guessing standard graphics2d.fill , setpaint methods may not sophisticated enough.
  • also, can recommend resources (preferrably free / online) learning more on this?

edit

some additional information: achieve flat fill effect below i'm creating area object , adding individual ellipse2d shapes using add(new area(ellipse)) , adding central polygon area avoid leaving white space in middle.

the iphone apps have access opengl-es allows significant latitude in shading , rendering coloured iso-surface emissive lighting. java2d not sophisticated enough unless willing write whole software 3d library it.

mixing 2d , 3d possible.

this question has answer here: how convert between big-endian , little-endian values in c++? 28 answers i've been looking around how convert big-endian little-endians. didn't find solve problem. seem there's many way can conversion. anyway following code works ok in big-endian system. how should write conversion function work on little-endian system well? this homework, since systems @ school running big-endian system. it's got curious , wanted make work on home computer also #include <iostream> #include <fstream> using namespace std; int main() { ifstream file; file.open("file.bin", ios::in | ios::binary); if(!file) cerr << "not able read" << endl; else { cout << "opened" << endl; int i_var; double d_var; while(!file.eof()) {...

i'm trying create application adheres following: no taskbar no console or form window can utilize console.writeline() . (i.e. if executes app command prompt write console.) the problem if create windows form (or wpf) application can have there no taskbar, console or window show up, console.writeline() nothing. if create console app, writes console, can't figure out how hide (and if did hide it, write command prompt window?)... how do this? just create standard console application. callers responsibility hide window caused program (from how run c# console application console hidden ): system.diagnostics.processstartinfo start = new system.diagnostics.processstartinfo(); start.filename = dir + @"\myprocesstostart.exe"; start.windowstyle = system.diagnostics.processwindowstyle.hidden;
