jogl - Viewing while sitting on a sphere -

-

In my JOGL program, I have (0,0,0) objects. I am using spherical coordinates to modify the angle (tilt) and f (rotation) to see my object on the original. But I am not able to see it properly. Occasionally the object disappears on some angles, and I can not see it from all angles. Here is my code: 

  zero decTheta () {theta--; East = Distance * Math.sin (Math. Tudian (Theta)) * Math.cos (Monastery (Fia)); Ez = Distance * Math.sin (Math. Tudian (Theta)) * Math.sin (Math.toRadiians (phi)); Ey = Distance * Math (Math. Tudian (Theta)); } Zero incTheta () {theta ++; East = Distance * Math.sin (Math. Tudian (Theta)) * Math.cos (Monastery (Fia)); Ez = Distance * Math.sin (Math. Tudian (Theta)) * Math.sin (Math.toRadiians (phi)); Ey = Distance * Math (Math. Tudian (Theta)); } Zero incPhi () {PHI ++; East = Distance * Math.sin (Math. Tudian (Theta)) * Math.cos (Monastery (Fia)); Ez = Distance * Math.sin (Math. Tudian (Theta)) * Math.sin (Math.toRadiians (phi)); Ey = Distance * Math (Math. Tudian (Theta)); } Zero decPhi () {PHi--; East = Distance * Math.sin (Math. Tudian (Theta)) * Math.cos (Monastery (Fia)); Ez = Distance * Math.sin (Math. Tudian (Theta)) * Math.sin (Math.toRadiians (phi)); Ey = Distance * Math (Math. Tudian (Theta)); }

What am I doing wrong?

Your purpose should be if you want to see it right and completely, then completely in your frustration Keep it working To modify your (perspective or orthogonal) projection matrix, I want to remind you that to use JOGL 2, a real understanding of OpenGL basics is required.

Editing Python Class in Shell and SQLAlchemy -

I am working on the terminal on a shell script after this tutorial SQLAlchemy tutorial. I need to type gt; & Gt; & Gt; Sqlalchemy import column, integer, string & gt; & Gt; & Gt; Class user (base): __tablename__ = 'users' id = column (integer, primary_key = true) name = column (string) absolute name = column (string) password = column (string) def __repr __ (self): return "& lt ; User (name = '% s', absolute name = '% s', password = '% s') & gt; "% (Self.name, self.fullname, self.password) After the problem I have typed the password = column (string) I hit twice and changed .... >> I then took everything back but then an error was thrown because the class already exists ... I am not completely sure how to fix it. How do I open that slip in the shell script and edit it (Add DF to DRR) The error thrown below: / user / giripeters / TFSQLLX / Lib / python2.7 / site-packages / sqlalchemy / ext / decla...

lua - HowTo create a fuel bar -

I would like to create a fuel bar (empty with full tank). When the user touches the screen, the fuel once Dairejh these is my code: lifeBar = display.newImage ( "fuel_bar1.png") lifeBar.anchorX = 0 lifeboats. ======================== Lifetime Y = 37 screens Group: The Insert function (called Laifbar) However, I fuel Kansmoshn (equivalent to "pressed" variable to reduce the fuel tank "true") Have used. When pressed == is true, it means that the user is touching the screen: processed (fuel) processed () if life & gt; 0 and pressed == true remains = life - life 1 Life = life =. Wide-1 remains Value.text = string.format ("% d", life) End of this This function is active as the entrance event: runtime: addEventListener ( "Antrfrem" fuel Snsadna) it is very well, but my question is: pressed variable each time 5 seconds (once = = True) How is it possible to reduce the vitality width? I tried to add it to my touch even...
