Need Intel Mac owners for screensaver test

[belthaczar]

Hi,

Could someone with an intel mac try to run this screensaver

Hydromancy1.3.dmg.gz (http://www.eecs.tulane.edu/Nguyen.Phillip/Hydromancy1.3.dmg.gz)

and then send me a crash log when it crashes system preferences?
It works fine on my g3 and I don't have access to an intel cpu to be
able to figure out what's going wrong. Thanks

Awesome screensaver, awesome pie chart control, doesn't crash my MacBook...

Crashed on my MBP. Here's the log; I hope it's what you're after.

Thanks! Hopefully I can get something out of it. At this point I have no clue.

[arekkusu]

Most likely you're asking GL to draw from memory that you don't own.
Start logging out your enabled arrays and the pointers before each draw call. Take a look at the number of vertices you're trying to draw vs how much memory you've actually allocated per array.

Could you try out this version and test if it still crashes for you?
HydromancyDebug.dmg.gz (http://www.eecs.tulane.edu/Nguyen.Phillip/HydromancyDebug.dmg.gz)

@arekkusu
So far all I can come up with is that in my call to glDrawRangeElements I specified a maximum array index which was 1 more than the actual size of storage. Though I never actually sent through any invalid indices. Does glDrawRangeElements immediately read in all the memory from the given start to end indices?

If this fix doesn't work, I can try to post some code.

Still crashes, I'm afraid.

Here's the log this time; I don't know if it's any different.

Okay, so I think my options at this point are to
1. switch to glDrawElements instead of glDrawRangeElements.
2. switch to glDrawElementArrayAPPLE if possible.

In one of my calls to glDrawRangeElements, there's a good chance
that I am exceeding GL_MAX_ELEMENTS_VERTICES. Could this be
causing the crash? From the docs I've read I thought that it would
just fall back to a slower implementation? Maybe I should not be
using glDrawRangeElements at all for that case.

If anyone wants to look at some code, I've packaged it all up here: HydromancySource.dmg.gz (http://www.eecs.tulane.edu/Nguyen.Phillip/HydromancySource.dmg.gz)

and I think these are the relevant portions:

from HydromancyPolygonize.h (declarations):

typedef struct {
float x, y; // coordinates of point
#ifdef HYDROMANCY_CHEESY_3D
float nx, ny, nz; // normal components
#endif
float val; // field value at point
int index;
RGB color; // color of point
} FIELDPOINT, *FIELDPOINT_PTR;

@interface HydromancyPolygonize : NSObject {
int m_xDivisions;
int m_yDivisions;
float m_xMax;
float m_yMax;

float m_isolevel;
char m_maxIterations;

BOOL m_ghostBlobMode;
BOOL m_wyvillBlobMode;
#ifdef HYDROMANCY_CHEESY_3D
BOOL m_cheesy3DMode;
#endif

Blob **m_blobList;

int m_meshRowSize; // need to keep this around to calculate indices
int m_meshSize; // need to keep this for zeroing vTable
FIELDPOINT *fieldPointCache; // stores calculated field point values
BOOL *vTable; // which field point values have been calculated?
char *sTable; // which squares have been subdivided (or rendered)?

FIELDPOINT m_vertlist[8]; // pool of vertices for constructing triangles

SQUARE subdivisionPool[POOLCAPACITY]; // pool of squares scheduled to be subdivided
SQUARE_PTR testPool; // pool of squares to begin testing for intersections
SQUARE_PTR fillPool; // pool of squares scheduled to be filled
int m_subdPoolCount; // number of squares in subdivisionPool
int m_testPoolCount; // number of squares in testPool
int m_fillPoolCount; // number of squares in fillPool
int m_fillPoolCapacity; // size of the fillPool.
}


from HydromancyPolygonize.m (initialization code):

- (id)initWithSettings :(float)xMax :(float)yMax :(int)yDivisions :(char)maxIterations
{
int meshColumnSize;

m_xMax = xMax;
m_yMax = yMax;
m_yDivisions = yDivisions;
m_maxIterations = maxIterations;

m_xDivisions = m_xMax * m_yDivisions / m_yMax; // multiply by aspect ratio

// The row size is 1 + xDivisions * 2^(maxIterations).
m_meshRowSize = 1 + (m_xDivisions << m_maxIterations);
meshColumnSize = 1 + (m_yDivisions << m_maxIterations);
m_meshSize = m_meshRowSize * meshColumnSize;

m_testPoolCount = 0;

// clear out any previous storage
if (fieldPointCache) free(fieldPointCache);
if (vTable) free(vTable);
if (sTable) free(sTable);
if (testPool) free(testPool);
if (fillPool) free(fillPool);

// Allocate storage for the fieldPointCache and vTable
// based on the mesh size for the deepest iteration. This is

fieldPointCache = (FIELDPOINT *)malloc(m_meshSize * sizeof(FIELDPOINT));
vTable = (BOOL *)malloc(m_meshSize * sizeof(BOOL));
sTable = (char *)malloc(m_meshSize * sizeof(char));
testPool = (SQUARE *)malloc(m_xDivisions * m_yDivisions * sizeof(SQUARE));
// The fill pool has an initial capacity equal to the number of root level squares.
// If we end up needing more capacity, we will realloc more later.
m_fillPoolCapacity = m_xDivisions * m_yDivisions;
fillPool = (SQUARE *)malloc(m_fillPoolCapacity * sizeof(SQUARE));

NSAssert(fieldPointCache, @"couldn't allocate memory for fieldPointCache");

NSAssert(sTable, @"couldn't allocate memory for sTable");

NSAssert(fillPool, @"couldn't allocate memory for fill pool");

glEnableClientState(GL_COLOR_ARRAY);

#ifdef HYDROMANCY_CHEESY_3D

#endif
glPolygonMode(GL_FRONT, GL_FILL);
if (!m_ghostBlobMode) {
glEnable(GL_BLEND);
} else {
glDisable(GL_BLEND);
}


[self initializeCache];

return self;
}


from HydromancyPolygonize.m (the problem):

- (void)divideAndConquer :(FIELDPOINT_PTR *)grid :(char)iteration :(unsigned char)boundaryFlag :(unsigned char)growFlag

...

if (!m_ghostBlobMode) {
glDrawRangeElements( GL_LINES,
0,
7,

// Store these values internally for the divide and conquer algorithm.

}


Does anybody see anything wrong with what I'm doing? Or should I just plain be doing it another way?

[belthaczar]

Ok, so since I'm still can't figure out what's wrong,
I've just replaced the glDrawRangeElements calls with
glDrawElements. If you still have the patience to
look at this, could you try it out and see if it is still
crashing?

Thanks,

Works perfectly. :) Great screensaver.

[belthaczar]

Finally something worked! Thanks for your help!

[iDevAwesomeGames]

Awesome screensaver!!! It works fine on my MacBook Pro 17" without crashing. I will be using this one from now on.

[Zwilnik]

So far so good on my Intel iMac (across 2 screens too)

[Tools10]

Looks really great except that I get some sort of dark-rectangels from time to time(there isn't a dark color in the colors option, looks like huge black pixels).

[toaster99]

Great screen saver works perfectly on my Intel Duo Mac Mini
