there go You well wrong to. How I it understood have, must You for a display-list using:

[web]https://wiki.delphigl.com/index.php/Displaylisten[/web]
with glNewList a new list started, these fill and then with glCallList Show.
Roland has but display-lists installed. Perhaps should You these using, instead of yourself which by API nachzubauen.

Hi!
glDrawArrays can in Displaylisten vorkommen.
but its task is it Vertex Data from Arrays quick from the main memory To draw.
Z.B can with a appeal 10000 Dreiecke at a single blow draw or in a Displayliste insert
Displaylisten go in memory the Grafikkarte held and are very quick but unfortunately suit tappt im dunkeln itself only for static Objects and the Space the Speichers is unfortunately terminable wants one now Animationen create
need is a speedy Possibility many 3D data new To draw.
these method:
rückgabe& =oGL(glBegin,~GL_QUADS)
oGL(glVertex3f,@Float(quad_A#, 0),@Float(quad_A#, 8),@Float(quad_A#, 16))
oGL(glVertex3f,@Float(quad_A#, 24),@Float(quad_A#, 32),@Float(quad_A#, 40))
oGL(glVertex3f,@Float(quad_A#, 48),@Float(quad_A#, 56),@Float(quad_A#, 64))
oGL(glVertex3f,@Float(quad_A#, 72),@Float(quad_A#, 80),@Float(quad_A#, 88))
rückgabe& = oGL(glEnd)
is for simply too slow ,glDrawArrays müste at least 10 time so quick his unless yet plenty faster .
unfortunately wisely I do not wieso The umsetzung the C Examples to XProfan not functions

C example :
glEnableClientState(GL_VERTEX_ARRAY);
glVertexPointer(3, GL_FLOAT, 0, vertex);
glDrawArrays(GL_TRIANGLES, 0, 6);

Hi!
can me Perhaps someone say as data the C Arrays in XProfan exactly nachgebildet go
can(must byte selfsame order in memory having) or which position each pieces the C Arrays in a area receive would.

for these Information would I very grateful.

C aray :
GLfloat vertex[4][3]={{-5.0f, 5.0f, 0.0f},
{-5.0f, -5.0f, 0.0f },
{5.0f, -5.0f, 0.0f },
{5.0f, 5.0f, 0.0f }};

well simply 8 byte per Float! 8x4x3
Compile Mark Separation

declare a#
dim a#,96
float a#, 0 =  blub
float a#, 8 =  blub
float a#, 16 =  blub

THX

On these manner have I it already attempts

Dim quad_A# ,120000
byt_count& = 0
Float quad_A#, (0 +byt_count&) = 0.0
Float quad_A#, (8 +byt_count&) = 1.0
Float quad_A#, (16+byt_count&) = 1.0
Float quad_A#, (24+byt_count&) = 0.0
Float quad_A#, (32+byt_count&) = 0.0

have no idea and so the "Riched not functions
have me yet on The hope clung that I the aray wrong equips have
but the is so well frail.

Mach time one lauffähiges Minimalbeispiel - from the too obviously is How You, the aray commit. and Codes Please always with

the first Program this Treads is the example Program
in the Procedure daten_init go the aray The pertinent data transfer.
The Procedure quad shows as they activate becomes as ausehen ought to.
unfortunately klapt it with the others method with glDrawArrays not the same to drawing .
if I whom first Float worth the Arrays of 0.0 on 1.0 change draw glDrawArrays something but not the right.
of these code becomes the aray the "Riched available set:
Compile Mark Separation

oGL(glEnableClientState,~GL_VERTEX_ARRAY)
oGL(glVertexPointer,3,~GL_FLOAT,0,@Addr(quad_A#))e>

yet is it I do not been successful The data in the aray so anzulegen that I the same ergebniss get How with the quad Procedure.though I already a great many different orders attempts have and so
I do not wisely whether I as a Error make or the Perhaps in Profan lying .

Try time with Doubles instead of with Floats!

Nachtrag I had here warscheinlich in the OGL-area a OGL-Source posted which to this principle a whole scene draw in the one itself too can move. even with reflection on the ground etc - look time in the OGL-area to Codes of me - Perhaps hilfts.

Andreas
Gaida

OK will be to whom Codes look

trouble resolved
Vielen Thanks IF
the hint with the Doubles has it brought do not have knew
the the C float only 4 Bytes has and went from the XProfan 8 Bytes from the muste Yes
Murks give
