c# - Increase distance when draw a ellipse -


how can increase distance when draw ellipse point? code use draw ellipse in c#:

public double[] calculateposition(double centerx, double centery, double angle) {     double[] position = new double[2];     position[0] = math.cos(angle) * radiusx + centerx;     position[1] = math.sin(angle) * radiusy + centery;     return position; }

draw ellipse based on point. function use this, draw example 5 ellipses, around point.

do mean size of eclipse? in case, want vary radiusx , radiusy.

the best way pass them parameters function:

public double[] calculateposition(double centerx,                                   double centery,                                   double radiusx,                                  double radiusy,                                  double angle) {     double[] position = new double[2];     position[0] = math.cos(angle) * radiusx + centerx;     position[1] = math.sin(angle) * radiusy + centery;     return position; }

then can draw several ellipses around same point calling function several times, , varying radiusx , radiusy.

c++ - Is it possible to compile a VST on linux? -

for class project i'm attempting write vst plugin backed cuda. current cuda workflow on linux box, i'd prefer compile , link there. according wikipedia , should possible (i couldn't find steinberg documentation relevant linux) can't find makefile or instructions on how build if aren't using xcode or visual studio. i'm vst 3 sdk doesn't support linux. when try compile plugin under linux, error: ./base/source/fatomic.cpp:39:30: fatal error: libkern/osatomic.h: no such file or directory this issue caused following code in "vst3 sdk/base/source/fatomic.cpp" #if mac #include <libkern/osatomic.h> #if mac_os_x_version_min_required > mac_os_x_version_10_4 #define native_atomic_type (volatile int32_t*) #else #define native_atomic_type (int32_t*) #endif #elif windows #include <windows.h> #endif but hope compiling under linux work vst sdk 2.4. reading. jvstwrapper seems run on lin...
