| DS_API void dsDrawBox | -( | -const float | -pos[3], | -|
| - | - | const float | -R[12], | -|
| - | - | const float | -sides[3] | - |
| - | ) | -- |
-Draw a box. -
-
| pos | is the x,y,z of the center of the object. | |
| R | is a 3x3 rotation matrix for the object, stored by row like this: [ R11 R12 R13 0 ] [ R21 R22 R23 0 ] [ R31 R32 R33 0 ] | |
| sides[] | is an array of x,y,z side lengths. |
| DS_API void dsDrawSphere | -( | -const float | -pos[3], | -|
| - | - | const float | -R[12], | -|
| - | - | float | -radius | - |
| - | ) | -- |

| v2 | third vertex | |
| solid | set to 0 for wireframe |
| DS_API double dsElapsedTime | -( | -- | ) | -- |
-Get the elapsed time (on wall-clock). -
-It returns the nr of seconds since the last call to this function. -
| DS_API void dsError | -( | -char * | -msg, | -|
| - | - | - | ... | - |
| - | ) | -- |
-exit with error message. -
-This function displays an error message then exit.
| msg | format strin, like printf, without the newline character. |
| DS_API void dsGetViewpoint | -( | -float | -xyz[3], | -|
| - | - | float | -hpr[3] | - |
| - | ) | -- |
-Gets the viewpoint. -

| - | - | - | ... | - |
| - | ) | -- |

-
| msg | format string, like printf, without the -. |
| DS_API void dsSetColor | -( | -float | -red, | -|
| - | - | float | -green, | -|
| - | - | float | -blue | - |
| - | ) | -- |
-Set the color with which geometry is drawn. -
-
| red | Red component from 0 to 1 | |
| green | Green component from 0 to 1 | |

| DS_API void dsSetColorAlpha | -( | -float | -red, | -|
| - | - | float | -green, | -|
| - | - | float | -blue, | -|
| - | - | float | -alpha | - |
| - | ) | -- |
-Set the color and transparency with which geometry is drawn. -
-
| alpha | Note that alpha transparency is a misnomer: it is alpha opacity. 1.0 means fully opaque, and 0.0 means fully transparent. |
| DS_API void dsSetSphereQuality | -( | -int | -n | -) | -- |
-Set the quality with which curved objects are rendered. -
-Higher numbers are higher quality, but slower to draw. This must be set before the first objects are drawn to be effective. Default sphere quality is 1, default capsule quality is 3. -
| DS_API void dsSetTexture | -( | -int | -texture_number | -) | -- |
-Toggle the rendering of textures. -
-It changes the way objects are drawn. these changes will apply to all further dsDrawXXX() functions.
| the | texture number must be a DS_xxx texture constant. The current texture is colored according to the current color. At the start of each frame, the texture is reset to none and the color is reset to white. |
| DS_API void dsSetViewpoint | -( | -float | -xyz[3], | -|
| - | - | float | -hpr[3] | - |
| - | ) | -- |
-Sets the viewpoint. -
-
| xyz | camera position. | |
| hpr | contains heading, pitch and roll numbers in degrees. heading=0 points along the x axis, pitch=0 is looking towards the horizon, and roll 0 is "unrotated". |
| DS_API void dsSimulationLoop | -( | -int | -argc, | -|
| - | - | char ** | -argv, | -|
| - | - | int | -window_width, | -|
| - | - | int | -window_height, | -|
| - | - | struct dsFunctions * | -fn | - |
| - | ) | -- |
-Does the complete simulation. -
-This function starts running the simulation, and only exits when the simulation is done. Function pointers should be provided for the callbacks.
| argv | supports flags like '-notex' '-noshadow' '-pause' | |
| fn | Callback functions. |
| DS_API void dsStop | -( | -- | ) | -- |
-Stop the simulation loop. -
-Calling this from within dsSimulationLoop() will cause it to exit and return to the caller. it is the same as if the user used the exit command. using this outside the loop will have no effect. -
