49. But you can
RECYCLE A LOT

50. 60 cm
50 mm
FROM MOBILE
90 mm
34 cm
and learn

51. Some words about
Graphics

52. The Scene Graph

53. Retained Mode
Rendering

54. SPEED
LIMIT
60

55. The Scene Graph
Each node is about 5-7 kb
★ Desktop could handle up to
100000 nodes
★ Embedded devices can
handle up to 1000 nodes !!!
★

56. But what does it
mean ?

57. To visualize
Data…

58. do we need this ?

59. isn't this enough ?

60. or what about this

61. or even this...

62. IT'S ABOUT
CONTENT OVER CHROME

63. But why is it
important ?

64. CONTENT
CHROME
3 Nodes
245 Nodes

65. CONTENT
COMPROMISE 1
3 Nodes
33 Nodes

66. CONTENT
COMPROMISE 2
3 Nodes
16 Nodes

67. CONTENT
COMPROMISE 3
3 Nodes
6 Nodes

68. Things you
BETTER AVOID

69. Things to avoid
huge amount of nodes
★ intense use of animations
★ intense use of effects
★ many overlapping nodes
★ memory intense operations
★

70. Some UI
Examples

71. Example UI (200 nodes)

72. Example UI (100 nodes)

73. Example UI (60 nodes)

74. Conclusion

75. JAVA(FX) ON EMBEDDED
really rocks...
